The master value was tuned for the old classical eval, the patch takes the roughly 2x slowdown in nps with SFNNUEv7 into account. This could reduce a bit the losses on time on fishtest, but they are probably unrelated. passed STC: https://tests.stockfishchess.org/tests/view/64bb8ae5dc56e1650abb1b11 LLR: 2.95 (-2.94,2.94) <-1.75,0.25> Total: 76576 W: 19677 L: 19501 D: 37398 Elo +0.80 Ptnml(0-2): 274, 8592, 20396, 8736, 290 closes https://github.com/official-stockfish/Stockfish/pull/4704 No functional change see source
