Strokes-gained by category
We weight SG:Approach + SG:Off-the-Tee + SG:Putting + SG:Around-the-Green by course demands. A U.S. Open course demands different skills than a short scoring course like TPC Summerlin.
Course fit
Same player, different venue, very different expected outcome. We track per-player course-fit scores by overlaying skill profile onto course characteristics (length, fairway width, rough height, green complexity).
Weather draw
Morning/afternoon AM-PM-AM-PM or AM-AM-PM-PM wave assignments matter. A bad weather draw (wind forecasted for your morning waves) can cost 1 to 2 strokes over 4 rounds vs a clean draw.
Recent form vs course history
Neither alone is enough. Recent form tells you how the player is playing right now; course history tells you whether the course fits them. Combine.
Travel and altitude
Players returning from Asia or Europe are meaningfully worse week-1 back. Altitude (Denver area) adds variance to the length game; some players adjust faster than others.
Weekend grind vs Thursday blitz
Some players consistently post their low round on Thursday, some on Saturday. Tracking round-specific scoring patterns creates edges in round-prop markets that full-tournament models miss.
