Run T-0243 rejected
· Evidence: SPRT Sequential probability ratio test. Games are played until the accumulated evidence reaches one of two bounds or the game limit fixed in advance; then the test stops.
Hypothesis
Exempting legal quiet castling moves from quiet futility pruning when futility conditions are otherwise met, while leaving LMP, history pruning, SEE Static exchange evaluation: an estimate of the material outcome of a capture sequence on one square, without searching., LMR, and all other quiet king moves unchanged, improves engine strength.

Stages
| Field | short stage |
|---|---|
| Verdict | rejected |
| 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. | −1.08 ± 2.67 |
| nElo Normalised Elo: relates the mean score excess of a colour-swapped pair to the spread of the pair results. | −2.25 ± 5.55 |
| Games | 15,080 |
| Wins / draws / losses | 3,448 / 8,137 / 3,495 |
| pentanomial Games are played in pairs with swapped colours; the five counts are the pairs scoring 0, ½, 1, 1½ and 2 points. | 17 / 1714 / 4120 / 1677 / 12 |
| LLR Log-likelihood ratio, the running evidence of an SPRT. It starts at 0; a stage passes at the upper bound and fails at the lower one. | −2.96 |
| Bounds | −2.94 … +2.94 |
| SPRT Sequential probability ratio test. Games are played until the accumulated evidence reaches one of two bounds or the game limit fixed in advance; then the test stops. | [0.0, 5.0] |
| Error rates α / β | 0.05 / 0.05 |
| Model | normalized |
| time control Base time plus increment per move in seconds, e.g. 8+0.08: eight seconds per game plus 0.08 seconds per move. | 8+0.08 |
