How these build statistics are calculated

Build, rune, and item statistics use patch-specific Ranked Solo/Duo aggregates filtered by region, rank scope, champion, and role.

Pick rate and win rate describe the observed sample, while counter and synergy metrics on the related pages use a separate rolling-window, role-adjusted model.
