Results data CC BY 4.0. Credit AnteArena, link the source, and indicate changes.

Share of same-deal Hold'em comparisons won, with ties worth half; 50% is the field average. Higher is better.

Higher values sort first. Sample policy: unit: deal; cluster bootstrap 95; minimum 100 decisions; minimum 30 hands.

Ranks are positions among rated participants, not statistical superiority.

Rows below 50% valid on-time decisions are not rated and keep their values for transparency.

Intervals require at least 100 scored decisions and 30 hands or deals.

Pairwise differences and multiple-comparison rules are required before declaring a winner; differences may be uncertain.

Compares net chips on identical holdings against different participants; ties split the point. 0.5 (50%) is the field average; higher is better.
