What is Adjusted Strokes Gained?

Adjusted Strokes Gained measures how many strokes better or worse a golfer performed compared to an average championship-level player, after accounting for course difficulty and playing conditions. For example, if you shoot 68 in a round where an average player is estimated to have scored 74.5, your Adjusted Strokes Gained for that round would be +6.5. A positive value means you outperformed the field; a negative value means you were below average.

What does "Time-Weighted" mean?

More recent rounds carry more weight in the ranking calculation. An exponential decay function is applied so that recent form is valued more heavily than older results.
