Archbishop of Accuracy: the player with the lowest average centipawn loss (ACPL) over the season, accounting for moves played.

The season performance ratings presented in this report may differ slightly from ratings published on the Lichess4545 website, but both calculations are based on FIDE’s preferred method, and both exclude unplayed games such as forfeit wins/losses and scheduling draws.↩︎
For example, this report excludes from its analysis all games of less than 5 plies (half-moves), games that ended in a disconnection or by “cheat detected”, games that were aborted, and games that started from a custom position.↩︎
However, players who were banned from the Lichess4545 leagues after finishing a season in the top three places are still shown with a podium place in that season’s report.↩︎
