Score Differential = (113 / Slope) × (Score − Course Rating). A lower differential = better round.
Handicap Index = average of the 8 best differentials from your last 20 rounds. With fewer rounds, the WHS ladder applies: 3 rounds → lowest − 2.0, 4 → lowest − 1.0, 5 → lowest, and so on up to 20+ rounds.
Course Handicap = HCP Index × (Slope/113) + (CR − Par), rounded.
This dashboard uses gross score directly. For fully accurate WHS calculation, scores should be adjusted to Net Double Bogey per hole — this is done automatically when you log hole-by-hole.

A spectator gets the live scoreboard on their phone — no friction, just open the link. If you and your opponent both add the round through Match Mode, both must confirm the result before it counts toward the Season.
