Details

• The rings are 8%, 16% and 28% of each distance — the first figure is for 50 yards, the second for 90.
• A rangefinder is easiest; a consistent pace will do.

If you are using a launch monitor or radar

• A monitor cannot score this game. Proximity is measured from the hole once the ball has stopped. Use it to set the two marks by carry.
• Do not take the yardages from a club-distance chart — those are total distance, not carry.
• Indoors, with no measurable resting place, this is the wrong test to run.

Retesting

• Warm up first — ten to fifteen balls with the club you will use. Same set-up, same ball, same conditions every retest. One run is a snapshot; two or three averaged is a standard.

Benchmark

• The benchmark is proximity from 50 to 100 yards, confirmed in the reference data. It is a band average, and this card averages a 50 and a 90 — the middle of that band — so the row applies as it stands. Each distance also shows its own first-ring rate.

Equipment

• Wedges · 20 balls · marks at 50 and 90 yards · rangefinder or a consistent pace. No specialist technology is required.
