methodology writeups
PGA uses 14+ custom metrics on top of strokes-gained, joined with weather and pin difficulty at the round level. LPGA uses L04 forward (player-mean) + L06 tournament Monte Carlo (10k sims, RMSE 2.85 strokes per round). Both face-validity tested — if a "clutch putter" metric ranked someone nobody would call clutch, it got cut.
