What is Adjusted share?
How much of the rating's weight came from rounds whose field strength was known and adjusted for. Below 100%, the remainder used the round's raw SG unadjusted — disclosed, never guessed.
How it's calculated
This is a count of the evidence behind another number, published so that the other number can be judged rather than taken on trust. It is derived by counting the rounds or events that actually fed the figure it accompanies — not estimated, and not smoothed. It is not a performance measure, it does not enter any ranking on this site, and a player is never advantaged or penalised for it. It exists purely so a reader can tell a well-supported number from a thinly supported one.
How to read it
Higher means more of the rating rests on rounds whose field strength was actually known, so the rating is better supported. A low share is a caution flag on the number beside it, not a mark against the player.
What it doesn't say
This is a reliability indicator, not an achievement. A large count does not make the underlying number good, only better supported; a small one does not make it wrong, only uncertain. Its purpose is to stop a striking figure built on a handful of rounds being read with the same confidence as one built on a full season. The most common mistake is to ignore it entirely and treat every number on a page as equally solid — which is exactly how an outlier from four measured rounds ends up quoted as though it described a player's true standard.
