Caddie Reference Card — The Scratch Project

📋 How to Personalise This Card — 10 Minutes, Once

This card is yours to fill in. Tap any number field and type your own values — they save automatically on this device. Wedges tab: run the Mevo Gen2 calibration session in Guide 51 (Gap Zone Mastery) or Guide 22 (Wedge Distances) and enter your real carry numbers for each clock position. Wind tab: no input needed — the calculator works from your wedge numbers automatically. Dispersion tab: enter your lateral spread from Guide 11 (Shot Dispersion) once you've logged 20+ rounds on Arccos. SG Targets tab: enter your current SG numbers from Guide 26 (Stats Interpretation) to track progress against your phase targets. Update every 6 months, after any equipment change, or after a launch monitor fitting (Guide 55).

Wind Reference Table — Tour Caddie Formula

Wind	Into (+)	Down (−)	@ 150 yds
10 mph	+10%	−5%	+15 / −8 yds
15 mph	+15%	−7.5%	+23 / −11 yds
20 mph	+20%	−10%	+30 / −15 yds
25 mph	+25%	−12.5%	+38 / −19 yds
30 mph	+30%	−15%	+45 / −23 yds

Other Conditions Adjustments

Temperature

±1–2 yds

Per 10°F from 70°F baseline. Cold UK day (45°F) = −5 yds approx.

Altitude

+2% / 1,000 ft

UK courses: negligible. Links at sea level = no adjustment.

Uphill

+1 yd / ft gain

Add slope elevation change to required yardage.

Downhill

−0.5 yd / ft drop

Subtract half the elevation drop from required yardage.

From Rough

−10–20%

Deep rough: −20%. Light rough: −10%. Less spin = more roll.

Firm Ground

+5–8 yds roll

Firm, dry conditions in summer. Aim short of flag — let it run.

Rule: Apply wind formula on EVERY approach when wind exceeds 10 mph — no exceptions. Guessing costs strokes. The formula takes 5 seconds.

Your Dispersion Profile (enter your own numbers)

Driver L/R

± yds

Aim to edge of fairway — allow full cone

7-iron L/R

± yds

Aim based on cone — not the flag

PW L/R

± yds

Always aim centre unless flag is fully open

Short Game

ft prox

Target average proximity from <50 yds

Aim Point Protocol

Driver

Aim to the edge of the fairway in the direction of your miss. If you miss right, aim right-centre of the fairway — never left rough to play a draw. The dispersion cone is your constraint.

Iron Approaches

Middle of the green unless the flag is in the open half AND you have at least 15 yards of green between flag and hazard. Tucked pins: always play to the fat side. Sucker pins: never attack.

Scoring Zone (<100 yds)

Choose the matrix distance that matches your required yardage. No improvised swings. If the required distance falls between two matrix entries, play the shorter one and allow for run.

Pin Categories

Category	Description	Target
Open	15+ yds of green beyond flag	Attack — aim at flag
Neutral	8–15 yds behind flag	Aim at flag, accept centre miss
Tucked	<8 yds behind flag or side hazard	Aim fat side of green
Sucker	Flag near hazard with no bail	Never attack — centre green only

Decision Framework

Step 1 — Assess

Lie → distance → wind → pin category → slope. Complete this in the same order every shot. Missing a step costs shots — usually wind or lie assessment.

Step 2 — Select

Use your matrix for wedge shots. Apply wind formula for approaches above 10 mph. Select aim point based on your dispersion cone, not the flag. Always take one more club than instinct says — you almost certainly under-club.

Step 3 — Commit

Pre-shot routine. Full commitment. Trust the number. The club selected after a complete assessment process is always the right club — don't second-guess at address.

Never Do These

🚫
Attack a sucker pin. One hero shot per round erases 3 good shots. Always take the fat side.
🚫
Under-club to a green with carry trouble. Take the club that gets you to the BACK of the green. Balls short of the green lose more strokes than balls over.
🚫
Skip the wind adjustment when it's "not that windy". 10 mph into adds 15 yards at 150. Always apply the formula.
🚫
Change the club selection at address. If you need to change clubs, step away and restart the routine. Never change at address.
🚫
Play a recovery shot heroically. From trouble, the target is: back in play, in the best possible position. Not birdies. Bogey elimination wins more shots than birdie attempts.
🚫
Skip the pre-shot routine when nervous. The routine exists specifically for when you are nervous. Abbreviating it under pressure is the most common cause of competition blow-ups.

Always Do These

✅
Aim using your dispersion cone. Not the flag. The flag is a reference point. Your aim point is where the centre of your cone needs to be.
✅
Apply the wind formula above 10 mph. Every single time. Build it as automatic habit by Round 20.
✅
Complete the pre-shot routine. On every shot. Including tap-ins. The routine is the protection against the unconscious shortcut that produces double bogeys.
✅
Accept the shot you just hit. Move forward in your routine immediately. Carrying the previous shot into the next decision contaminates the assessment process.
✅
Hit the percentage shot from trouble. Sideways or backwards to a good lie is always the right play. Calculate the expected score from both options if needed — the conservative option wins.

Double-Bogey Elimination Protocol

When in Trouble

Ask: what shot makes a double bogey impossible? Not what shot makes birdie possible — what removes the worst outcome? Execute that shot. At 10 HCP, 3.2 double bogeys per round are the single biggest scoring leak. Eliminate one per round and your handicap drops immediately.
