The interesting and useful part is it's stage 2 with 5,000,000.

In two days (e.g.), I found three factors to the following numbers in the 2M range with B1=50,000 (and B2=5,000,000):
2526553
2399933
2560849

That was lucky, of course. But I've been doing that for a long time now and found a lot of factors in that time.
