What is Adjusted true SG?
Skill rating from the tour's published per-round strokes gained: each measured round is adjusted for the strength of the field it was earned against, recent rounds count more (180-day half-life over a 2-year window), and thin samples are shrunk toward the tour average. Higher is better; +2 means about two strokes per round better than an average tour player.
A disclosed model over published SG — see the methodology page. Players under 12 measured rounds are not rated at all rather than rated on noise.
How it's calculated
Strokes gained is computed by the PGA Tour from ShotLink-measured rounds. Every shot is compared with what the field average would have taken from the same place — the same distance, the same lie, the same surface — and the difference is credited to the player. Summed over a round, that is how many shots better or worse than the field they played. OTIS restates the tour's published per-round figures; it does not recompute them.
How to read it
Higher is better. It is a skill rating rather than a result: it asks how good the player has shown themselves to be, weighted toward recent evidence and adjusted for the strength of the fields those rounds came in.
What it doesn't say
Strokes gained is a comparison, not an absolute: a positive figure means better than the field that week, so the same play can produce different numbers in different fields. It also needs a real sample. Putting in particular swings enormously over a handful of rounds, and a hot fortnight on the greens tells you far less about a player than the same gain in approach play would. A blank is not a zero — it means the rounds were never ShotLink-measured.
