Error in Low Composite Cleanup page
At this moment I'm running P-1 algorithm on the range M16.0 using bounds B1 = 1M, B2 = 500M.
I found that the numbers in the columns named Low P-1 and Avg B2 in https://www.gpu72.com/low/ do not...

There is a missing comma in the first line: 4,209961,589,561,203

Maybe this is useful: I'm working on he range 14.1M which is similar, and I'm using the bounds B1 = 2M, B2 = 1G. I reserved 20 GB of RAM for Prime95. I found more than 40 factors in the last month.
