INTELLIGENCE

How the numbers are made.

Player DNA, Course DNA and Course Fit are descriptive, versioned and built only from observed results.

PLAYER DNA

golf-results-dna/1.0.0

Dimension	Unit	Definition
Scoring vs field	strokes per round better than the round field average	Mean of (round field average − player round score) across rounds in full-field leaderboards. Positive = better than the field. Equivalent in construction to round-level total strokes gained; no per-shot categories.
Consistency	standard deviation of field-adjusted round scores	Sample standard deviation of the player’s field-adjusted round results. Lower = more consistent.
Under-par rounds	% of rounds	Share of observed full-field rounds completed under the published par.
Cuts made	% of starts	Starts in full-field leaderboards where the player completed all scheduled rounds.
Top-10 rate	% of starts	Starts in full-field leaderboards finishing tenth or better (ties included).
Contention	% of starts	Starts in full-field leaderboards finishing fifth or better (ties included).
Recent form	strokes per round vs field, last 10 full-field starts	Scoring vs field restricted to the player’s ten most recent full-field starts before the as-of date.
Major performance	strokes per round vs field in majors	Scoring vs field restricted to major championships with full-field leaderboards.

Confidence tiers: rounds — High ≥ 40, Medium ≥ 20, Limited ≥ 8; starts — High ≥ 12, Medium ≥ 6, Limited ≥ 3. Percentiles are mid-rank within one division and window, withheld below Limited or when fewer than 10 players qualify. Windows: last 24 months and all observed since 2000. Only results that ended before the as-of date are used.

COURSE DNA

golf-course-dna/1.0.0

Scoring difficulty, spread and under-par rate come from every round in full-field editions at the venue, compared with other courses in the same division. Winning score and cut line use published values. Each edition’s published setup is a separate layout version.

COURSE FIT

golf-course-fit-descriptive/1.0.0

Descriptive components only: course history, performance on comparably difficult setups, performance on comparable lengths and recent form. Each shows the player value, the course signal and both samples. There is no composite score and no win probability.
