Run T-0165 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 a parent node tracks a child node's reduction, and the child adjusts its search depth accordingly—increasing it by one if it was heavily reduced and the move did not statically weaken the moving side, or decreasing it by one if both static evaluations show the move caused significant harm—the engine will play stronger under time controls.

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. | −2.74 ± 3.67 |
| 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. | −5.30 ± 7.12 |
| Games | 9,144 |
| Wins / draws / losses | 2,163 / 4,746 / 2,235 |
| pentanomial Games are played in pairs with swapped colours; the five counts are the pairs scoring 0, ½, 1, 1½ and 2 points. | 34 / 1124 / 2321 / 1066 / 27 |
| 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; 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 |
