Report for the second half of 56 M (B1=B2≤700,000): 2 factors found out of 35 attemps (5.71%). Expected prob. 3.93%~3.94%.
Now intending to work on the exponents in the first half of 57 M that has B1=B2≤700,000 and without a DC. I will reserve every exponent as TF before I start my work on it, so you don't have to avoid them.
Currently informally "reserved":
 the first half 56 M (B1=B2≤690,000)
Currently planning to do (will Primenetreserve every exponent):
 the first half 57 M (B1=B2≤700,000)

Reason: typo: min prob is 3.93
