Increase null verification threshold to 12 plies Increasing depth limit to 10 plies seems stronger after 16K games at 15"+0.05 (ELO: +3.56) and also repeating the test at 60"+0.05 TC: ELO: 2.08 +-3.1 (95%) LOS: 90.9% Total: 16000 W: 2641 L: 2545 D: 10814 Moreover setting the limit to 12 is proved stronger then limit set to 10 by direct SPRT test at 15"+0.05: ELO: 2.56 +-2.0 (95%) LOS: 99.5% Total: 46568 W: 9240 L: 8897 D: 28431 So we directly set the limit to 12, the strongest setup. bench: 4361224
