How it plays

Not what the scorecard says — what this course does to the same players, measured against everywhere else they play. Built from 2,084 rounds across 7 editions, and ranked against every course in the archive.

Measure	Versus elsewhere	Which means	Across the archive
Driving distance	−7.4 yds	shorter off the tee here	8th shortest of 89
Fairways hit	+7.2 pp	easier to find	12th easiest to find of 89
Greens in regulation	+7.1 pp	easier to hit	6th easiest to hit of 88
Scrambling	+0.6 pp	easier to save par	middle of the pack

Scoring. These players average 1.31 shots fewer per round here than they do elsewhere.

Plays most like. Sedgefield, TPC River Highlands, Sherwood — the closest courses in the archive on those four measures together.

A record of what happened, not a forecast. Estimates are shrunk toward the tour mean by how much evidence each course has, and every baseline leaves the course itself out, so a venue cannot define the average it is measured against. Split-half reliability 0.888. Weather is not controlled for.

The week, round by round

Scoring average for each round of the tournament, drawn against this course’s own four-round average. Round 2 has played 1.37 of a shot easier than round 3, the widest gap in the week.

Longer to the right is easier scoring than a typical round here; longer to the left is harder. Built from 1,503 rounds — every player who completed an edition at this course, counted in all 4 of his rounds. Only finishers are in it, because Thursday is played by the whole field and Sunday by the half of it that survived the cut: compare those as they fall and every course on tour looks like it eases off for the weekend. Weather is not controlled for, so a single storm-hit afternoon is in these numbers along with everything else.

Who has played above themselves here

Strokes gained per round at this course against the same player’s own average everywhere else. Being a good player is not enough to appear on this list — the comparison is with himself, so what is left is the part that belongs to the course.

Player	Rounds here	Here	Elsewhere	Gap
Mackenzie Hughes	17	+1.70	+0.22	+0.61
J.T. Poston	17	+1.45	+0.44	+0.42
Joel Dahmen	14	+1.26	+0.14	+0.41
Eric Cole	12	+1.71	+0.50	+0.40
Will Gordon	14	+0.92	-0.11	+0.38
Henrik Norlander	14	+0.97	+0.03	+0.35

The gap is pulled toward zero by how few rounds sit behind it, so a player seen four times here does not outrank one seen twenty. Read it as a record, not a projection: players who keep coming back to a course are partly the ones it has already suited, and that selection is inside these numbers.

What the data says

Across 7 editions (2019–2025), approach play is the category that most separates players who contend here from those who do not — 26% of the model's weighting, against 24% for putting.

The spread is narrow, which is itself the finding: this course does not strongly favour one kind of player. Weights this close to even mean the field sorts mostly on overall quality, and any course-fit edge here is small.

The winners tell a partly separate story: in 4 of the last 6, the champion's best category for the week was putting. That differs from what the model weights, and the gap is instructive — winning weeks are outlier weeks, usually powered by one skill running hot on top of the baseline the course demands.

How the winners won

Strokes gained per round for every champion here since 2019. The highlighted figure is that winner's best category for the week. A dash means the category split is not published for that event — only the total is.

Method. Weights come from regressing top-20 finishes on players' strokes gained in each category, using only rounds played before each event, and comparing each course against the tour-wide baseline — so a weight measures what this course rewards more than golf generally does, not simply which skills help. Weights are kept only where they predicted results out of sample; where they did not, we say so. We tested our previous method, found it did not predict, and published that too: how the model works.
