Golf course analytics
Every other asset on your property gets measured. Your golf course gets opinions.
Most golf analytics measures players. FogBow measures the golf course.
Independent measurement of how your course actually plays, from the rounds your members already posts. FogBow sells no equipment and has no stake in what the numbers say.
What measurement looks like
Two findings that bear directly on a member club. The wider set (50 championships across 4 papers, 3 of them posted open access and reproducible from deposited data) sits on the methods page and in the fixed-venue study. The method that produced them is the method run on a member club.
Figure 1 comes from the fourth paper, which is a working draft; its data opens when the paper does. FogBow LLC is not affiliated with or endorsed by the United States Golf Association; Course Rating and Slope Rating are USGA trademarks, used here only to refer to the USGA’s ratings.
Questions your committee cannot answer today
What a club receives
A written report
Findings first, then the exhibits behind them, and an honest account of what the data will not support. Short enough that a committee reads it, complete enough that a doubter can check it.
Nine optional modules
Handicap integrity, competition fairness, setup consistency, tee fit, hole locations, maintenance impact, monitoring, renovation effect, pace of play. See all nine, with the exhibit each produces →
A tier, private by default
Your course on the four-tier scale of measured difficulty from the published U.S. Open study. Yours alone unless you choose otherwise. Clubs opt in to the public table, and can leave at any time. How the tiers work →
Evidence, not opinion
Every method is checked first against data whose answer is known in advance, so a finding is shown to be recoverable, not merely produced.
A stroke index that holds up
Allocated hole by hole from your own scoring, for each tee set, under WHS Appendix E, with an annotated card showing where it differs from today’s.
A baseline you keep
The measured starting point, in a form that can be re-run next season or either side of a renovation.
Three ways to buy, and why the last one takes three seasons
Each tier answers a different question. They are bought separately and in any order, though most clubs begin at the left.
Three seasons
Course Calibration Report
Where your golf course actually plays against the rating it was assigned, measured on the rounds your members already posted.
Answers: where do we stand?
Chosen as needed
Nine Modules
One question each, bought individually. Handicap integrity, renovation before-and-after, stroke index allocation, aerification recovery, and 5 more. See all nine →
Answers: one specific thing, properly.
Every season, ongoing
The report, maintained
The same measurement, repeated annually by the same method, so that what changes at the golf course is the only thing that moves in the number. Three quantities accumulate as the seasons add up, and together they are your course's Signature.
Answers: what is this course doing over time?
No new method is sold in year 3 that was withheld in year 1. How hard the course plays is in your first report. How much it moves is variation between seasons, so 1 season contains none of it and 2 or 3 estimate it loosely. What moves it sharpens the same way: the first report separates conditions from everything else, and more seasons separate setup from agronomy from who played. What is bought is continuity — the same measurement, made the same way, by somebody who does not rotate off the committee.
Questions committees ask, including the structural test for whether a club is a good fit, are answered on the FAQ page. The 9 modules, with the exhibit each produces, are on the modules page.
Who does the work
FogBow is the work of Junaid Mohiuddin, who originated the analysis it is built on and developed the framework it applies: three decades building and auditing measurement systems, over a decade on golf committees, and four papers on championship venue difficulty.
