Course Management & Decision-Making

The Management Framework

Course management is the application of probability and expected value to every shot decision. At club handicap level, poor decision-making costs an estimated 3–5 strokes per round — more than most technical deficiencies. You cannot out-swing bad decisions.

📊 Expected Value Thinking

The Core Principle

Aim Where You Can Afford to Miss

Every shot has a dispersion cone — a realistic spread of outcomes around your intended target. Course management is not about where you want the ball to go. It is about where your worst acceptable outcome lands, and whether that outcome is recoverable.

The Decision Framework

Best case outcome: where does a perfect shot finish?
Worst case outcome: where does a miss finish?
Expected value: weighted average across both

→ If worst case = double bogey or worse, reconsider the target.

Tour caddies think about worst-case outcomes first. Amateurs think about best-case outcomes first. This single mental shift is worth 2–3 strokes per round.

The Strokes Gained Decision Model

Every Decision Has a Measurable Expected Value

Situation	Conservative Play	Aggressive Play	Verdict
160 yds, water left, bunker right	Centre green: avg 2.4 putts	Flag hunt: 30% water = +0.6 strokes	Conservative +0.4 SG
Par 5, 240 yds to carry bunker	Layup to 100 yds: avg 4.8	40% in bunker: avg 5.1	Layup +0.3 SG
Par 4, tight tee, OOB right	3-wood: 88% fairway	Driver: 55% fairway, 12% OOB	3-wood +0.5 SG
150 yds, open flag, firm green	Centre green	Attack flag: 65% green	Marginal — judge by short game

Double Bogey Elimination Rule

The Single Biggest Score Saver at Club Level

Score Distribution — Typical Club Handicap Round

Eagles

~0.05/rnd

Birdies

~1.2/rnd

Pars

~8–9/rnd

Bogeys

~6–7/rnd

Doubles+

~3.2/rnd

⭐

The rule: Before every shot, ask — "Can this decision result in a double bogey or worse?" If yes, reconsider. Eliminating 2 doubles per round saves ~2 strokes immediately — without improving a single technical skill.

Your Dispersion Cone — Know It, Use It

The Foundation of Every Target Decision

Club	Club HCP Dispersion (L/R)	Tour Dispersion	Practical Implication
Driver	±35–50 yds	±15–20 yds	Need 70–100 yds of fairway to aim centre
5-iron / hybrid	±25–35 yds	±12 yds	Centre green minimum from 180+ yds
8-iron	±18–25 yds	±8 yds	Can attack accessible pins from 140 yds
PW	±12–18 yds	±5 yds	Can attack most pins from 120 yds and in

Tee Shot Strategy

The tee shot sets up the entire hole. Every tee strategy decision must account for hazard positions, landing zone width, miss direction, and approach angle preference.

🏌️ Tee Box Decision System

The Five Tee Shot Questions

Answer These Before Every Drive

1
What is the dominant miss? Your natural shot shape determines which side of the fairway is safe. Never aim toward your miss — use it.
2
Where is OOB or the penalty hazard? OOB costs stroke + distance. Any hole with OOB on one side demands your tee shot plays away from it, even at the cost of a worse angle.
3
What landing zone width is available? If the fairway at your carry distance is narrower than your realistic spread, use less club to land in a wider zone.
4
What is the ideal approach angle? Think backward from the flag to the tee. The correct side of the fairway on a dogleg can add 15–20 yards of distance advantage.
5
What club gives the best risk/reward? A 3-wood to the ideal position in the fairway is worth more expected value than a driver into rough or a hazard.

Tee Box Positioning

Use the Full Tee Box Width

Hazard Position	Tee Position	Aim	Outcome
Trouble right (OOB, water)	Right side of tee box	Down the left centre	Miss left = rough; miss right = back toward centre
Trouble left (OOB, water)	Left side of tee box	Down the right centre	Miss right = rough; miss left = back toward centre
Trouble both sides (tight par 4)	Centre, toward stronger miss side	Widest part of fairway	Maximise landing zone; accept shorter club
Dogleg right	Right side of tee box	Left edge of dogleg	Opens the hole; avoids cutting corner trees
Dogleg left	Left side of tee box	Right edge of dogleg	Opens the hole; avoids cutting corner trees

When Driver Is Wrong

Club Selection off the Tee

1
Fairway width under 30 yards at carry: 3-wood or hybrid. 20 extra yards of driver distance is worthless from the rough at 200+ yards.
2
OOB present on either side: Stroke + distance is a 2-shot penalty. Conservative club selection is mathematically correct.
3
Short par 4s under 320 yards: Driver can carry through or leave an awkward partial wedge. Hybrid to a full wedge distance is frequently the better play.
4
After a bogey or worse: Error rates increase 18% on the hole immediately following a double. Take one club less and aim at the widest part of the fairway.

Approach Shot Management

The approach shot is where scoring is built or destroyed. Pin position, green slope, miss direction, and realistic carry distance must all be integrated into a single target decision.

🎯 Approach Decision System

The Four Pin Categories

Not All Pins Are Equal — Target Selection by Risk

Pin Category	Definition	Club HCP Target	Tour Target
Open	15+ ft from all edges, no short-side danger	Attack flag	Attack flag
Neutral	10–15 ft from edge, mild short-side	Fat side of flag	Attack flag
Tucked	5–10 ft from edge, hazard or rough short-side	Centre green	Fat side of flag
Sucker	Under 5 ft from edge, severe penalty short-side	Opposite side of green	Centre green

⭐

Tour data: The best approach players in the world aim away from tucked and sucker pins on approximately 40% of approach shots. If they aim away, so should you.

Club Selection — The Under-Clubbing Epidemic

The Most Expensive Habitual Error

1
Use average carry, not best carry: Your best 7-iron might go 165 yards. Your average carry is likely 152–158 yards. Always club to your average — the course plays averages, not bests.
2
Add one club as default: Until your real carry distances are verified on the Mevo, add one club to whatever feels right. 65% of amateur approach shots are short of the flag.
3
Account for conditions: Into wind (+10–30%), cold (−5–12%), uphill (+1 yd/ft), wet rough (−15–20% carry).

Layup vs. Attack

Every decision to lay up or attack must be based on expected value — not ego, momentum, or emotion. The data consistently shows amateur golfers attack too often and lay up too rarely.

⚖️ Expected Value Framework

The Layup Decision Matrix

When to Lay Up — Data-Driven Thresholds

Scenario	Go if Carry Confidence	Lay Up if Below	Lay Up Target
Par-5 in 2, no penalty	75%+ confident in carry	Below 75%	Wedge distance from front edge
Par-5 in 2, water front	90%+ confident	Below 90%	50–80 yards from green
Dogleg carry cut	80%+ confident	Below 80%	Short of hazard with full fairway
Approach over water	85%+ confident in carry	Below 85%	Pitch to lay-up zone, accept bogey target

💡

The ego trap: Most amateur golfers estimate their carry confidence at 80% when it is actually 55%. Measure your actual carry percentage for specific shots using tracked data before assigning a confidence number. Gut feel overestimates by 15–25% consistently.

Optimal Layup Distance

Where to Lay Up for Maximum Scoring Advantage

Most amateurs lay up to an "iron distance" without considering that their scoring zone — the distance at which they produce their best proximity — is specific and measurable from their Arccos or Shot Scope data.

1
Identify your proximity sweet spot: Check your SG: Approach data by distance band. If your best proximity is from 90–110 yards, lay up to that distance — not to 130 yards because it's a "full shot."
2
Avoid awkward distances: The 40–70 yard range is the hardest in golf for most amateurs — it requires a partial swing with a high-loft wedge. Lay up to either under 30 yards (pitching wedge chip) or beyond 80 yards (full wedge) whenever possible.
3
Account for the lie: A layup that leaves the ball in a divot, rough, or sidehill lie is inferior to a shorter layup on a clean, flat fairway. Always sacrifice 10–15 yards for a perfect lie over an awkward lie at the optimal distance.

Scoring Zone Management

Inside 100 yards is where scores are made or saved. Managing the scoring zone requires landing zone discipline, spin awareness, and the understanding that proximity from inside 100 yards is the highest-leverage SG category for a player targeting scratch.

🏆 Proximity Framework

Scoring Zone Proximity Targets

What You Need to Hit to Achieve Scratch

Distance	Tour Avg	Scratch Target	Club HCP Typical
30 yards	5 ft	<8 ft	12–16 ft
50 yards	8 ft	<12 ft	18–24 ft
75 yards	11 ft	<16 ft	26–32 ft
100 yards	15 ft	<20 ft	35–42 ft

Scoring Zone Decision Rules

Inside 100 Yards — Never Attack a Sucker Pin

1
Inside 100 yards, pin is always accessible: This does not mean attack every flag. It means the distance is not the limiting factor — the pin position and your spin/trajectory control are. Always know your spin capability before attacking.
2
Land zone first, flag second: From every scoring zone distance, identify your landing zone first. The flag is where you want the ball to finish — the landing zone is where you aim. Always separate these two targets.
3
Short-side rule: From inside 100 yards, short-siding yourself is a 0.4–0.6 SG loss on average for an amateur. The worst miss is always the one that leaves the most difficult chip — identify that side before selecting your target.

Target Optimisation — The Probability Approach

Scott Fawcett's Decade system, built on Mark Broadie's Strokes Gained research, shows that the standard amateur aim point — "middle of the green, work the miss" — significantly underperforms a probability-weighted target calculation. The insight: aim point should not be determined by where you want the ball to go, but by the expected score across your full shot distribution from that lie and distance. The two answers are rarely the same.

📐 The Maths of Target Selection

Why Intuitive Aim Points Underperform

The Problem With "Middle of the Green"

1
Green centre is only optimal when consequences are symmetrical: "Aim at the middle" assumes that a miss left and a miss right are equally costly. They almost never are. A miss into a bunker costs 0.6 expected strokes more than a miss onto the fringe. A short-side miss costs 0.4 strokes more than a long-side miss. When consequences are asymmetric — which is almost always — the optimal aim point shifts away from centre toward the lower-cost miss side.
2
Your dispersion cone is not centred on your aim point: Most amateur golfers have a systematic directional bias revealed by 20+ rounds of tracking data (Guide 11). A player who aims at the green centre but has a 65% miss-left pattern is effectively aiming left of centre. The optimal aim point starts from where the centre of your actual distribution lands — which for most players is not the same as their intended aim point.
3
Distance gapping is more important than lateral precision at most amateur distances: Strokes Gained research consistently shows that the single biggest decision error at amateur level is not left-right aim but short-long. Players systematically under-club, landing short of the green at rates far higher than landing long. The first correction to make is almost always one club more, targeting the back half of the green.

The Decade Framework — Applied

Calculating Your Optimal Aim Point in 4 Steps

1
Step 1 — Know your total dispersion at this distance: From your Guide 11 dispersion mapping and Arccos Air SG: Approach data, identify your total lateral dispersion (in yards) at the distance of the shot. At 150 yards, a typical club player has approximately 55–65 yards total lateral dispersion (±27–32 yards). This is your cone width.
2
Step 2 — Identify the consequences of each miss direction: For this specific flag position, what happens if you miss left vs. right vs. short vs. long? Assign a rough expected score to each miss quadrant: green fringe (best), rough but open (moderate), bunker or rough with obstacle (worse), water or OB (worst). You are building a consequence map, not just a green map.
3
Step 3 — Shift the aim point toward the lower-consequence side: If missing right puts you in a bunker (−0.6 strokes vs fringe) but missing left leaves a short pitch from thin rough (+0.1 strokes vs fringe), your optimal aim point shifts left of your natural instinct — even if that means a slightly longer putt on a well-struck shot. You are optimising the distribution, not the perfect outcome.
4
Step 4 — Club up by default: In all but the most specific circumstances (firm greens running away, water long), the shot that lands short of the green produces a worse expected score than the shot that lands long. Club up until you have a reason not to, not down until you have a reason to go more. This single habit, applied consistently over 18 holes, is typically worth 0.5–0.8 SG: Approach per round.

The Flag Attack Decision — When to Go, When to Play Away

A Probability Framework for Pin Decisions

Pin Position	Accessible If...	Aim Point if Not Attacking	When to Never Attack
Front edge, tucked	Carry is precise AND green holds	Back-centre — accept longer putt	Into the wind, firm greens, any doubt on carry
Middle of green	Almost always — optimise long vs. short	Back half of green	When bunkers surround — then play to best miss side
Back pin	With correct club — aim at flag	Front-centre	Water long — club down 1, aim front half
Short-side pin (tight to bunker)	Only if ≥70% confident in precise carry	Away side — 20 feet away is better than sand	Always play away if SG: APP trend is negative
Diagonal pin (corner of green)	Never directly attack diagonal pins	Aim at the diagonal centre — gives equal miss room both ways	Always — this is the highest-risk flag category

Applying This With Arccos Air

Using Your Actual Data to Build Personal Aim Points

1
Pull your approach proximity by distance band: In Arccos, Analytics → Approach → Proximity by Distance. Your average proximity at 125–150 yards, 150–175 yards, 100–125 yards. This tells you how your dispersion translates to real approach proximity — the number you actually need for aim point calculations.
2
Check your miss pattern: Analytics → Approach → Miss Pattern. What percentage left, right, short, long? If 45% of your misses are short, the most impactful aim point adjustment is simply taking more club — no lateral recalculation needed. Most players are surprised by the short miss percentage.
3
Build 3 personal rules from the data: After 20+ rounds: (a) your default club adjustment ("always add 1 club at 150+ yards"), (b) your systematic miss direction adjustment ("aim 5 yards right of centre"), (c) your confidence threshold for attacking pins ("only attack pins with >6 yards of margin between target and hazard on my miss side"). Three rules, applied consistently, produce more improvement than complex hole-by-hole calculations.

Conditions Management

Course conditions — wind, firm or soft ground, wet surfaces — change the SG value of every decision. The player who adapts strategy to conditions consistently outperforms the player who plays the same game regardless of what the course presents.

🌬️ Wind Strategy

Wind Percentage Formula

Quantifying Wind Effect on Club Selection

Tour Caddie Wind Rule

Into wind: add 1% of carry distance per mph of headwind
Downwind: subtract 0.5% per mph of tailwind

Example: 150-yard approach into 15 mph headwind
Addition: 150 × 0.01 × 15 = 22.5 yards → play 173 yards

Wind	Add (Into)	Sub (Down)	150 yd Effect
10 mph	+10%	−5%	+15 / −8 yds
20 mph	+20%	−10%	+30 / −15 yds
30 mph	+30%	−15%	+45 / −23 yds

Firm vs. Soft Ground Strategy

Ground Conditions Change the Game Completely

Condition	Tee Strategy	Approach Strategy	Short Game Adjustment
Firm, fast	Driver more often — bounce adds distance	Land short, use bounce; one less club	Bump-and-run preferred; land short of flag
Soft, wet	3-wood acceptable — no bounce gain	Fly ball to flag; one more club for soft landing	Flop and pitch preferred; land at flag

Hole Type Strategies

Different hole configurations require systematically different management. A player who approaches every par 4 identically — regardless of its shape, hazard placement, and scoring difficulty — leaves significant strategic value on the table.

🏌️ By Hole Configuration

Par 3 Strategy

Club to the Fat Part of the Green

1
Never attack a tucked par-3 pin: The expected score from a par-3 approach to the fat side of the green is better than attacking a tucked flag for most club handicap players. Short-siding on a par 3 is the most common double-bogey trigger.
2
Always take enough club: Par 3s play long because of nerves, cold, and wind. Add one club minimum as a default. A ball short of a par-3 green is a near-certain bogey; a ball over is recoverable.
3
Identify the bail-out area before hitting: Every par 3 has a best miss direction — the area from which the par save is easiest. Aim slightly toward that area from the flag.

Long Par 4 Strategy (430+ yards)

Bogey Is Your Friend — Par Is Bonus

1
Set bogey as the target score: On a 440-yard par 4, your most likely score is a bogey. Plan for a bogey without embarrassment — set up your tee shot and approach to make bogey the most likely outcome, not to chase a par that requires everything to go right.
2
Keep the ball in play: On a long, difficult par 4, the primary tee shot criterion is avoiding penalty. Driver into trouble adds a shot and changes the psychology of the hole. 3-wood to the fairway is almost always the correct play.

Par 5 Strategy

Three Shot Holes Offer the Best Birdie Opportunity

1
Decision 1 — go in 2?: Apply the layup decision matrix from the previous tab. If confidence is below 90% over water or 75% without penalty, lay up. Par 5 birdies are most reliably achieved with a good layup and quality wedge — not with hero shots.
2
Layup distance discipline: Always lay up to your best proximity distance from your SG data — not simply to "a full shot." Leaving the ball at 90 yards when your best proximity comes from 70–80 yards costs strokes.
3
Aggressive short game, conservative long game: The combination of conservative long game (no penalty attempts) with aggressive short game (attack accessible par-5 pins from your wedge distance) is the most reliably birdie-producing strategy at amateur level.

Approach Miss Direction

Pre-selecting a miss direction on every approach shot is the highest-precision course management skill. It converts a random error into a planned error — and a planned error from the right side of the green is worth 0.3–0.6 SG compared to an unplanned short-side miss. This section provides the complete system.

📐 The Miss Direction Framework

Why Miss Direction Matters More Than Miss Distance

The Short-Side Penalty — Quantified

Research on amateur scoring patterns shows that a short-side miss (within 5 feet of the edge of the green, on the pin side) costs an average of 0.4–0.7 more strokes per hole than a miss to the fat side — from the same approach distance. The short-side chip or pitch requires maximum precision (tight lie, flag close, often over a bunker) while the fat-side miss leaves a simpler, longer chip with more green to work with.

Miss Type	Average Recovery Proximity	Up-and-Down Rate (Club Level)	Expected Score Impact
Fat side miss (15–25 ft chip)	12–18 ft	32%	−0.1 vs. GIR from same distance
Long (over green, open)	15–22 ft	26%	−0.2 vs. GIR
Short-side miss (tight chip)	22–35 ft	14%	−0.5 to −0.7 vs. GIR
Short-side, bunker between ball and flag	28–45 ft	9%	−0.8 to −1.0 vs. GIR

🎯 The Green Zone System — Miss Direction by Pin Position

Green Divided Into Nine Zones — Aim Point by Pin Location

Where to Miss Based on Where the Flag Is

Divide the green into a 3×3 matrix: front/middle/back (depth) and left/centre/right (lateral). For each pin position, there is a pre-defined aim point that maximises the probability of a recoverable miss when the shot is executed within your normal dispersion range.

Pin Position	Primary Aim Point	Acceptable Miss	Avoid at All Costs
Front-left (tucked)	Centre-right of green, 10–15 ft long	Right side, middle depth	Short-left (bunker or tight lie)
Front-centre	Centre green, 12–18 ft long	Either side, middle depth	Short of green (any side)
Front-right (tucked)	Centre-left of green, 10–15 ft long	Left side, middle depth	Short-right (bunker or tight lie)
Middle-left	Right-centre, at flag depth	Right side, any depth	Left edge (short-side)
Middle-centre (open)	Attack flag — this is the only time you aim directly	Any miss is acceptable	No must-avoid — open pin
Middle-right	Left-centre, at flag depth	Left side, any depth	Right edge (short-side)
Back-left (tucked)	Centre-right, front half of green	Right side, middle depth — accept long putt	Long-left (over green, short-side)
Back-centre	Centre green, middle depth — accept long putt	Either side, back half	Over green long (lost ball/bunker)
Back-right (tucked)	Centre-left, front half of green	Left side, middle depth — accept long putt	Long-right (over green, short-side)

📊 Hazard Weighting — Adjusting for Specific Danger

When Hazards Override the Standard Miss Direction

Water, OOB, and Severe Rough — Re-weighting the Decision

1
Water on one side: The standard miss direction is overridden entirely. Any shot where a miss puts the ball in water or OOB demands aiming 15–25 yards away from the hazard, regardless of where the pin is. A double-bogey from a water penalty costs more expected strokes than any short-side chip. Always play away from penalty hazards on approaches — no exceptions.
2
Bunker between ball and flag (short-side): When the bunker is short-side between you and a tucked flag, the miss direction is emphatically long. A bunker miss from a tucked flag is one of the most costly short-game scenarios in golf — long misses leave a straightforward chip. Aim for the back third of the green on any approach where a bunker guards the short-side.
3
Severe rough only on one side: Thick, penalising rough on one side of the green demands aiming away from it — even at the cost of a longer putt. A 30-foot putt from the fat side is worth more expected strokes than a 15-foot chip from heavy rough. Check your short game SG data to confirm which lies are most costly for your game.

🧠 Pre-Shot Integration — How to Use This System Every Hole

The 20-Second Pre-Shot Miss Direction Protocol

Adding Miss Direction to Your Approach Routine

1
Identify pin zone (2 seconds): Is the flag front/middle/back and left/centre/right? This is a quick visual read from behind the ball.
2
Identify hazards (3 seconds): Is there water, OOB, or a bunker that overrides the standard miss direction? If yes, the hazard side is automatically the "never miss" side.
3
Select aim point (5 seconds): Using the Green Zone System table, identify your aim point and set your intermediate target accordingly. This may be 10–15 feet away from the flag.
4
Commit and execute (10 seconds): Once the aim point is selected, do not second-guess. The whole value of pre-selecting a miss direction is that you execute with full commitment — no in-swing target changes. A committed shot to the right aim point is always better than a hesitant shot toward the flag.

⭐

The mental shift: Implementing miss direction thinking requires accepting that you will sometimes aim 15 feet from the flag and hit it close — at which point the aim point feels conservative in hindsight. This is normal and correct. The system is calibrated to your long-run performance, not to individual shots. Over 18 holes and 100 approach shots, playing to the right aim point consistently outperforms "always aim at the flag" by 1.5–2.5 strokes per round at this handicap level.

Tracking Your Miss Patterns — Using Shot Scope and Arccos

Building a Personal Miss Direction Profile

Your miss direction system should be calibrated to your actual miss pattern — not to a generic right-hander's tendency. Use your Arccos or Shot Scope miss plot data to determine:

1
Your primary miss direction: Is your systematic miss left, right, short, or long? If 65% of your approach misses are left, your aim point should bias further right than the standard system suggests.
2
Your miss by club category: Many players miss in different directions with irons vs. hybrids, or long irons vs. short irons. Build a per-club miss profile and adjust aim points accordingly.
3
Review monthly: As your technique improves through this programme (particularly face control and wrist mechanics), your miss pattern will change. Recalibrate your aim points quarterly using the most recent 3 months of tracked approach data.

On-Course Management Drills

Three structured practice drills that convert the management frameworks in this guide into personal data. Each requires committing to a defined strategy — then measuring what the data shows.

🎮 Scoring Simulations

Drill 1 — Par-3 Simulation Game

18-Hole Range Scoring with Consequence

1
Designate a specific range target as a par-3 green. Choose a yardage in your 6–8 iron range — ideally where your dispersion data shows a genuine miss pattern. This is your "hole" for the session.
2
Play 18 simulated par-3 holes. Tee each ball (or use a rubber tee equivalent at the range). Play your "tee shot," then from where it lands, simulate a chip or putt to complete the hole. Score: eagle = −2, birdie = −1, par = 0, bogey = +1, double+ = +3.
3
The scoring consequence changes everything. A specific shot with a meaningful score attached forces the pre-shot routine, aim point decision, and commitment level that a practice ball fired casually at a flag cannot replicate. This is the missing element in most range sessions.
4
Benchmark target: Under +4 for 18 holes at your current handicap level. Tour players average approximately −18 for 18 par-3 holes at 6-iron distance. Track monthly — improvement in this simulation correlates directly with par-3 scoring on course.

Drill 2 — Par-5 Strategy Experiment

Maximum Aggression vs Structured Layup — Personal Data

1
On your home course, play every par-5 twice over two consecutive rounds. Round 1: maximum aggression — go for the green in 2 whenever it is physically reachable (regardless of hazard, carry requirement, or miss consequence). Round 2: structured layup — always lay up to your optimal wedge distance from the guide (typically 80–100 yards).
2
Record the score on every par-5 in both rounds. After both rounds, calculate your average par-5 score for each strategy. Most players discover their intuitive par-5 strategy is either measurably too conservative (layup average better than aggressive by 0.3–0.5 strokes) or measurably too aggressive (aggressive average worse by 0.5–1.0 strokes).
3
Use the data to set a personal par-5 policy. If layup consistently outperforms, adopt the layup as your default and reserve the go-for-it play for holes where the risk-reward is demonstrably positive (short carry, no penalty, wide green). This converts a philosophical debate into a data-driven rule.

💡

SG context: Tour players gain approximately 0.5 SG per round on par-5s versus the field average. At 10 handicap, par-5 strategy decisions account for an estimated 1.5–2.5 shots per round. This experiment quantifies your personal version of that gap.

Drill 3 — Post-Round Decision Audit

Separating Decision Quality from Outcome

1
After every competitive round, identify 3 shots where you made a club or strategy decision. These should be moments where you had a genuine choice — not the automatic play — and made a deliberate call. Approach selection, layup vs attack, club selection into a par-3, tee club on a tight hole.
2
For each decision, write three things: (a) What you chose and why. (b) What the EV-optimal choice was using the framework in Guide 40 — best expected outcome given your actual dispersion, not your hoped-for dispersion. (c) Whether the outcome matched the decision quality.
3
Track across 10 rounds. Look for repeating patterns: a specific hole where you consistently make the EV-negative choice; a club you systematically over-rely on; a situation (tight tee shot, par-3 over water) where fear consistently overrides the process. These patterns are where your management game is costing shots — and unlike technique, they can be fixed immediately with a single pre-round commitment.
