· 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
Replacing the baseline term RfpFaktor*tiefe in the reverse futility pruning margin with floor(RfpFaktor*tiefe*(RfpTiefe+tiefe)/(2*RfpTiefe)), while continuing to subtract steigend_abschlag and the conditional RfpGegner penalty before clamping at zero, improves engine playing strength.

Stages
| Field | short stage | long stage |
|---|---|---|
| Verdict | passed | passed |
| 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. | +3.95 ± 2.93 | +3.49 ± 2.79 |
| nElo Normalised Elo: relates the mean score excess of a colour-swapped pair to the spread of the pair results. | +8.09 ± 6.01 | +7.27 ± 5.81 |
| Games | 12,852 | 13,734 |
| Wins / draws / losses | 3,060 / 6,878 / 2,914 | 3,106 / 7,660 / 2,968 |
| pentanomial Games are played in pairs with swapped colours; the five counts are the pairs scoring 0, ½, 1, 1½ and 2 points. | 12 / 1411 / 3435 / 1555 / 13 | 3 / 1506 / 3710 / 1646 / 2 |
| 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 | +2.71 |
| Bounds | −2.94 … +2.94 | −1.34 … +2.71 |
| 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] | [0.0, 5.0] |
| Error rates α / β | 0.05 / 0.05 | 0.05 / 0.25 |
| Model | normalized | 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 | 40+0.4 |
