Tweak reductions formula: 0.88 * depth + 0.12 Replace the depth part in the reduction formula for higher depths with a slower growing linear function. So for depth > 3 less reductions are used. What we can try next: - move the break point to even higher depths - tweak the slope for lower and higher depth - even possibly use a further higher depth threshold for a another slower growing function STC: LLR: 2.95 (-2.94,2.94) [0.00,5.00] Total: 25317 W: 5763 L: 5505 D: 14049 LTC: LLR: 2.96 (-2.94,2.94) [0.00,5.00] Total: 7451 W: 1320 L: 1167 D: 4964 Closes Bench: 4617359
