Run T-0248 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
During search, non-tactical PV Principal variation: the line of best moves the search currently expects. moves receiving an extension are buffered. After history updates, a history penalty scaled by depth is applied to each of these buffered moves that did not turn out to be the best move. This modification is expected to increase playing strength.

| 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. | −3.10 ± 3.77 |
| nElo Normalised Elo: relates the mean score excess of a colour-swapped pair to the spread of the pair results. | −6.19 ± 7.53 |
| Games | 8,188 |
| Wins / draws / losses | 1,892 / 4,331 / 1,965 |
| pentanomial Games are played in pairs with swapped colours; the five counts are the pairs scoring 0, ½, 1, 1½ and 2 points. | 15 / 1004 / 2127 / 935 / 13 |
| 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. | −2.95 |

| 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] |

| 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 |
