Tweak reduction formula based on depth The idea came to me by checking for trends from the megafauzi tunes, since the values of the divisor for this specific formula were as follows: stc: 15990 mtc: 16117 ltc: 14805 vltc: 12719 new vltc passed by Muzhen: 12076 This shows a clear trend related to time control, the higher it is, the lower the optimum value for the divisor seems to be. So I tried a simple formula, using educated guesses based on some calculations, tests show it works pretty fine, and it can still be further tuned at VLTC in the future to scale even better. Passed STC: LLR: 2.94 (-2.94,2.94) <0.00,2.00> Total: 431360 W: 110791 L: 109898 D: 210671 Ptnml(0-2): 1182, 50846, 110698, 51805, 1149 Passed LTC: LLR: 2.94 (-2.94,2.94) <0.50,2.50> Total: 114114 W: 29109 L: 28625 D: 56380 Ptnml(0-2): 105, 12628, 31101, 13124, 99 bench: 2273551
