Model score

Backtest · reconstructed

Our course-fit model re-run as it would have seen this week — using only data that existed before the first tee shot — then compared with how the 72 players actually finished. It was not published in advance, so this measures the model, not a call we made.

Dgrade

Rank correlation: +0.241
Top-20 hit rate: 40%
Top-10 avg model rank: 28.4

Grade is this event’s percentile (25th) against every other event we have scored — not an absolute pass mark. Rank correlation runs −1 to +1, where 0 is a coin flip and a full-field golf model landing near +0.35 is a genuine read.

One known caveat. Player stats, form and course history are all restricted to what existed before this event. The course archetype is not — it is derived from the venue’s full history, including this edition. That flatters the model slightly and equally at every venue. How the model works.

OTIS ranks every field on how well each player's game matches the course, then prices their chances. Both are published in full and graded afterwards.
