What is Trend?
Baseline minus form: positive means the player is beating their own 12-month norm — trending hot.
A score-based proxy, not Strokes Gained — the tour does not publish per-round SG at usable granularity.
How it's calculated
This is computed by OTIS from stored round scores rather than published by the tour. A player's recent scoring is measured against their own trailing twelve-month average, so the comparison is with themselves rather than with the field. Only stroke-play rounds count; team and match-play results do not produce comparable scores.
How to read it
Positive means the player is currently scoring better than their own twelve-month normal. It measures change, not quality — a positive figure from a modest player still describes a modest player, improving.
What it doesn't say
Form is a short-window measure and therefore a volatile one: it is designed to move, and a player at the top of it is not necessarily one of the better players on tour, only one playing better than they usually do. Because the comparison is against a player's own baseline, an improving journeyman can outrank a world-class player in an ordinary patch. It also uses raw scores, so an easy stretch of the schedule flatters it.
