What is Poa scoring?
Average round score at courses with poa annua greens (the bumpy, late-day west-coast surface) — lower is better.
Raw stroke-play round scores at poa-green courses; shown only with a meaningful sample.
How it's calculated
This is computed by OTIS rather than published by the tour: each of the player's stroke-play rounds is attributed to the green surface of the course it was played on, and the scores are averaged by surface. It uses actual round scores rather than strokes gained, so it covers players without ShotLink-measured statistics.
How to read it
Lower is better. Poa surfaces get bumpier as the day goes on, which is why players often describe them as the hardest to putt in the afternoon.
What it doesn't say
The surface a player scores well on is confounded with the courses that use it. Bermuda greens are common in the south and poa on the west coast, so a green-type average partly measures which tournaments a player enters and how strong those fields were, not just how they putt on that grass. Treat it as a hypothesis worth checking against strokes gained on putting, not as proof that a surface suits somebody.
