Ranks are positions among registered participants. Intervals are block bootstrap 95% intervals, not proof of statistical superiority. Conditions and fairness
This game measures executing a known optimal policy exactly and adapting it to the cards already seen; arithmetic reliability over many small decisions. What each game measures
Shared axis: bet units. The vertical ink line marks zero.

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.
A missing value means the required observations were unavailable.
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.
