They were then interleaved together. The idea was to give Wrong_NNUE.binpack closer to equal weighting with the Training _Data binpack . nn-6ad41a9207d0.pt was derived from a net vondele ran which passed STC quickly, but faltered in LTC. https://tests.stockfishchess.org/tests/view/60cba666457376eb8bcab443 STC: LLR: 2.95 (-2.94,2.94) <-0.50,2.50> Total: 18792 W: 2068 L: 1889 D: 14835 Ptnml(0-2): 82, 1480, 6117, 1611, 106 https://tests.stockfishchess.org/tests/view/60ccda8b457376eb8bcab568 LTC: LLR: 2.94 (-2.94,2.94) <0.50,3.50> Total: 11376 W: 574 L: 454 D: 10348 Ptnml(0-2): 4, 412, 4747, 510, 15 https://tests.stockfishchess.org/tests/view/60ccf952457376eb8bcab58d closes https://github.com/official-stockfish/Stockfish/pull/3568 Bench: 4900906
