Run T-0049 passed

2026-08-31 · Evidence: SPRT Sequential probability ratio test. Games are played until the accumulated evidence reaches one of two bounds; then the test stops.

Hypothesis

Probing current-generation transposition bounds in quiescence and prioritizing a matching tactical table move should reduce repeated evaluation, move-generation, and SEE Static exchange evaluation: an estimate of the material outcome of a capture sequence on one square, without searching. work without replacing deeper principal-search entries.

Predecessor set to: T-0049

Stages

Point estimate with the reported 95-percent half-width, per stage. The dashed line is zero. Estimates from a stopped sequential test are biased by the stopping rule; the interval is nominal.

Elo Strength difference to the opponent, estimated from the games, with a 95-percent half-width where the oracle reported one. Never an absolute rating.	+4.79 ± 3.80	+1,194.89
nElo Normalised Elo: the Elo difference divided by the spread of the game results, so that the SPRT bounds mean the same at different time controls.	+6.08 ± 4.82	+7,659.38 ± 30.89

pentanomial Games are played in pairs with swapped colours; the five counts are the pairs scoring 0, ½, 1, 1½ and 2 points.	`970 / 2100 / 3629 / 2229 / 1043`	`0 / 0 / 0 / 1 / 242`
LLR Log-likelihood ratio, the running evidence of an SPRT. It starts at 0; a stage passes at the upper bound (about +2.94) and fails at the lower one (about −2.94).	+2.96	+2.95
