Here's one example: With sigma=1459848859275459, Prime95 v22.12 finds the factor 777288435261989969 of M1123: in stage 1 with B1 >= 535489 in stage 2 with B1 >= 38917 & B2 >= 534241 I'm not entirely sure why the B2 required to find the factor at the end of stage 2 is smaller than the B1 required to find it in stage 1. One of the improvements I guess.
