A wallet's win rate in a sport or category used to refresh once an hour. It now updates a few minutes after any of that wallet's markets resolves, and the category rankings built from those rates move with it.
You see the change everywhere the number appears: the sport win rate on sharp wallet chips across the sports boards, Game View, and event pages; the category records on trader profiles; the leaders on every category page; the category columns on the leaderboard; and the expert check behind the Pick of the Day. A wallet that just closed a run of tennis markets shows its new rate before the next match starts, instead of after the hour turns.
