· 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 sufficiently deep non-PV Principal variation: the line of best moves the search currently expects. node without a TT Transposition table: a cache of already searched positions, keyed by a hash of the position. move is reduced by exactly one level, the worse-ordered search costs less and the saved budget can produce additional depth at more important nodes.
translated from German. Original: Wenn ein ausreichend tiefer Nicht-PV-Knoten ohne TT-Zug um genau eine Stufe reduziert wird, kostet die schlechter geordnete Suche weniger und das gesparte Budget kann an wichtigeren Knoten zusätzliche Tiefe erzeugen.
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. | +7.60 ± 5.35 | +16.22 ± 8.31 |
| 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. | +9.78 ± 6.88 | +21.79 ± 11.15 |
| Games | 9,790 | 3,730 |
| Wins / draws / losses | 3,364 / 3,276 / 3,150 | 1,272 / 1,360 / 1,098 |
| pentanomial Games are played in pairs with swapped colours; the five counts are the pairs scoring 0, ½, 1, 1½ and 2 points. | 436 / 1052 / 1758 / 1160 / 489 | 123 / 404 / 694 / 464 / 180 |
| LLR Log-likelihood ratio, the running evidence of an SPRT. It starts at 0; a stage passes at the upper bound (about +2.94) and fails at the lower one (about −2.94). | +2.95 | +2.97 |
| Bounds | −2.94 … +2.94 | −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] | [0.0, 5.0] |

| 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 |
