They were then interleaved together. The idea was to give Wrong_NNUE.binpack closer to equal weighting with the Training_Data binpack passed STC: https://tests.stockfishchess.org/tests/view/60d0c0a7a8ec07dc34c072b2 LLR: 2.93 (-2.94,2.94) <-0.50,2.50> Total: 18440 W: 1693 L: 1531 D: 15216 Ptnml(0-2): 67, 1225, 6464, 1407, 57 passed LTC: https://tests.stockfishchess.org/tests/view/60d762793beab81350ac9d72 LLR: 2.98 (-2.94,2.94) <0.50,3.50> Total: 93120 W: 3152 L: 2933 D: 87035 Ptnml(0-2): 48, 2581, 41076, 2814, 41 passed LTC (rebased branch to current master): https://tests.stockfishchess.org/tests/view/60d85eeb3beab81350ac9e2b LLR: 2.96 (-2.94,2.94) <0.50,3.50> Total: 42688 W: 1347 L: 1206 D: 40135 Ptnml(0-2): 14, 1097, 18981, 1238, 14. closes https://github.com/official-stockfish/Stockfish/pull/3592 Bench: 4906727
