P1 found a factor in stage #1, B1=759000.
UID: Jwb52z/Clay, M105269581 has a factor: 6228935338450361187678798473 (P1, B1=759000) 92.331 bits. This is the highest bit level one I've had in a while, especially in stage 1.

These 500K exponents are a gold mine.
M538751 has a 132.045bit (40digit) factor: 5617865834413045127033000770286991147617 (P1,B1=10000000,B2=1110000000) New personal best! I am doing the P1 with bounds as mentioned > B1=10,000,000, B2 is automatic. This results in about 1.35 GHzD of work, on average. If anyone wants to look for potentially really big factors, I recommend B1=25,000,000, at least. I think I am going to change it to that value right now...

I am planning on getting to 1M exponents someday, where I've already started P1, but I went to 500K because I thought those should also be lifted.

Meanwhile... Oh, you generated your B2s yourself. I let Prime95 generate them. So that's probably the main difference. You can simply use this tool on mersenne.ca here. You can set your exponent range and B1, and it will generate worktodo lines for you. You only need to delete those which already had a bigger B1 done. Or use a script for them...
