What is Form?
Recent form as a difficulty-adjusted strokes-gained figure: each recent round scored against how hard it actually played, with the latest starts weighted most and thin samples pulled toward the field average.
Backed out of published round scores via a round-difficulty regression (no per-round SG feed is required); small-sample players are shrunk toward an average-tour-player baseline so noise can't spike them.
How it's calculated
This is part of the course-fit model — the one place on OTIS where published numbers are combined into a score of our own, rather than restated. The components are shown separately so a total can always be taken apart into skill, venue fit and recent form. It is labelled as a model wherever it appears.
How to read it
Higher is better. It is difficulty-adjusted, so a good round on a hard day counts for more than the raw score suggests.
What it doesn't say
This is a modelled number, not a published one, and it is a ranking device rather than a prediction. It says a player's game matches what a venue has rewarded historically — nothing about injuries, weather on the day, or form that has not shown up in the data yet. Small gaps between adjacent players are noise, and venues with little hosting history produce weaker-supported scores than long-standing hosts.
