Run T-0132 rejected
· Evidence: SPRT Sequential probability ratio test. Games are played until the accumulated evidence reaches one of two bounds; then the test stops.
Hypothesis
If every completed iteration stops the search as soon as the elapsed time plus the duration of the last iteration reaches the soft time target, even after a best move change or an evaluation drift over 50 cp, instead of relying solely on the hard limit of three times the soft target in these cases, the engine plays stronger than the baseline across all time controls.

|---|---|
| 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. | −9.93 ± 6.30 |
| 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. | −18.25 ± 11.57 |
| Games | 3,464 |
| Wins / draws / losses | 768 / 1,829 / 867 |
| pentanomial Games are played in pairs with swapped colours; the five counts are the pairs scoring 0, ½, 1, 1½ and 2 points. | 30 / 450 / 866 / 361 / 25 |
| 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. | −2.97 |
| Bounds | −2.94 … +2.94 |
| SPRT Sequential probability ratio test. Games are played until the accumulated evidence reaches one of two bounds; 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 |
