Formulas

Reference for the Riccio models used by this calculator. Baseline and Advanced tabs show the answer only — the maths lives here.

Baseline (Eq. 1) (GIR only)

Score = 95 − 2 × GIR

Riccio’s Rule. Greens in regulation are the strongest single predictor of score. Used on the Baseline tab.

Advanced (Eq. 9) (GIR + putts)

Score = 58 + Putts − (4/3) × GIR

Combines GIR with actual putts. Used on the Advanced tab when putts are entered.

Expected putts (Eq. 7)

Expected Putts = 37 − (2/3) × GIR

Expected putts given your GIR. On Advanced, the Putts diff bubble shows whether you are even with, above (+), or below (−) that expectation.

Driving categories and driver carry inform practice insights and skill brackets only; they do not change these score equations.

Tee Box Helper

Quick Yes/No club pick for the tee. Laser penalties first. Metres default — switch units anytime.

Driver carry (m)

Closest fairway hazard carry (m) Laser the closest carry hazard. Compare it to your driver carry.

Tip: Penalty lines first. Bunkers/waste matter for land/roll — not always a penalty stroke.
