Increase slowmover and reduce instability These two changes go in opposite directions and it seems that the combination is stronger than original. Here are the positive tests at various TC: 15+0.05 LLR: 2.96 (-2.94,2.94) [-1.50,4.50] Total: 24561 W: 4946 L: 4772 D: 14843 60+0.05 LLR: 2.96 (-2.94,2.94) [0.00,6.00] Total: 15259 W: 2598 L: 2423 D: 10238 40/30 LLR: 2.96 (-2.94,2.94) [-3.00,3.00] Total: 2570 W: 527 L: 422 D: 1621 Unfortunately there is also a bad result with one sec time increment that needs to be further investigated: 12+1 LLR: -2.97 (-2.94,2.94) [-3.00,3.00] Total: 2694 W: 438 L: 543 D: 1713 bench: 8340585
