Peer Comparison

You vs your rating band. Move by move.

Every stat in the Leak Finder is overlaid against players of your exact rating band, in your time class, against opponents in your bracket. If your Rook + Pawn conversion rate at Blitz is 68% and your peers convert 78%, you know exactly what to work on — and how much you'd gain by fixing it.

Peer baselines are recomputed monthly from a corpus of 1.5M+ analyzed games across 2,000+ players.
