Since on average they make pawn history more negative offset is changed to lower value to remain average value approximately the same. https://tests.stockfishchess.org/tests/view/664b3af9830eb9f886614aab Passed STC: LLR: 2.93 (-2.94,2.94) <0.00,2.00> Total: 170464 W: 44239 L: 43724 D: 82501 Ptnml(0-2): 523, 20278, 43128, 20767, 536 Passed LTC against pending PR : https://tests.stockfishchess.org/tests/view/664b8c58830eb9f886614b64 LLR: 2.94 (-2.94,2.94) <0.50,2.50> Total: 98178 W: 25015 L: 24569 D: 48594 Ptnml(0-2): 48, 10769, 27005, 11223, 44 closes https://github.com/official-stockfish/Stockfish/pull/5275 Bench: 1343175
