My notebooks are just spitting out factors these two days……expected rate should be about 3.8%, according to https://www.mersenne.ca/prob.php.

I'm working on a range that should have close to a 3% (1/33) success rates.
The factor number and corresponding attempt numbers so far are:
1st: 28
2nd: 55
3rd: 263 (At this point 1/88)
4th: 321
5th: 334
6th: 343 (Better: 1/57)
7th: 482 (1/69)
.......520 (1/74 and counting)

far above the B2, and close to the exponent.
