Every category weighted equally. This course has not accumulated enough history for its weights to be tested, so we do not score course fit here.

How it plays

Not what the scorecard says — what this course does to the same players, measured against everywhere else they play. Built from 867 rounds across 2 editions, and ranked against every course in the archive.

Measure	Versus elsewhere	Which means	Across the archive
Driving distance	+0.6 yds	longer off the tee here	middle of the pack
Fairways hit	−0.6 pp	harder to find	middle of the pack
Greens in regulation	−0.7 pp	harder to hit	middle of the pack
Scrambling	−0.2 pp	harder to save par	middle of the pack

Scoring. These players average 0.02 shots more per round here than they do elsewhere.

Plays most like. Caves Valley, Bellerive, St. George's G&CC — 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.

What it has taken

The numbers the week has actually demanded, edition by edition, counted from the scores rather than from anyone’s summary of them. The cut line is the worst halfway score that still saw a Saturday.

The week, round by round

Scoring average for each round of the tournament, drawn against this course’s own four-round average. Round 1 has played 1.58 of a shot easier than round 4, 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 540 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.

What the data says

We do not publish a course-fit read for Hurstbourne Country Club. Venue weights are kept only where they predicted results on seasons the model had never seen, and this course has not yet accumulated enough history to clear that bar — 2 editions in the archive.

That is deliberate. It would be easy to generate confident-looking numbers from 867 rounds of scoring data; they would just not mean anything. Until the signal is testable, every category is weighted equally here and course fit is not scored. The winners below are still worth reading as history — they are simply not a forecast.

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.

Year	Winner	To Par	OTT	APP	ARG	PUTT	Total
2026	Steven Fisk	-16	+0.76	+1.08	+0.05	+0.85	+2.74

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.
