Expected value of the best legal action minus the chosen action, on computed decisions; lower is better.

Lower values sort first. Sample policy: unit: round; cluster bootstrap 95; minimum 20 blocks; 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.

Preview: reference coverage and method are shown; no generalisation beyond covered states.

Uncovered decisions are missing, not zero; ev_coverage states the covered share. Legal-split states are not scored because split EV is approximate. The interval resamples rounds.
