Adjust scale param higher xoto10's scaleopt tune resulted in a yellow LTC, but the main parameter shift looked almost exactly like the tune rate reduction schedule, so further increases of that param were tried. Joint work xoto10 and dubslow. passed LTC: https://tests.stockfishchess.org/tests/view/628c709372775f382300f03e LLR: 2.93 (-2.94,2.94) <0.50,3.00> Total: 70112 W: 18932 L: 18584 D: 32596 Ptnml(0-2): 66, 6904, 20757, 7274, 55 failed STC: https://tests.stockfishchess.org/tests/view/6290e4441e7cd5f29966bdc8 LLR: -2.96 (-2.94,2.94) <0.00,2.50> Total: 59976 W: 15919 L: 16018 D: 28039 Ptnml(0-2): 250, 6791, 15974, 6754, 219 similar LTC's were yellow first yellow LTC: https://tests.stockfishchess.org/tests/view/6288a33f817227d3e5c5b05d double exaggerate yellow: https://tests.stockfishchess.org/tests/live_elo/628e140372775f38230129a6 triple exaggerate yellow: https://tests.stockfishchess.org/tests/live_elo/628e2caf72775f3823012d45 closes https://github.com/official-stockfish/Stockfish/pull/4036 bench 6410652
