Error in Low Composite Cleanup page
At this moment I'm running P1 algorithm on the range M16.0 using bounds B1 = 1M, B2 = 500M.
I found that the numbers in the columns named Low P1 and Avg B2 in https://www.gpu72.com/low/ do not change except when a new factor is found. This means that all numbers in those columns appear to be wrong. I'd appreciate a fix for this problem. Last fiddled with by alpertron on 20220426 at 12:48

Thanks for the update.
Notice that in the range 49.x the Avg B2 values are wrong if the numbers in the Low P1 column are correct.

I've just imported the factoring limits report from 49.9M to 50M (the URL is https://www.mersenne.org/report_fact...99&tftobits=72) to Excel.
I found that there are only two exponents for which B2 > 100M: M49917871 and M49930021. Since there are 1980 numbers with no known factors in this range, I would expect the low P1 column for the last row of the table to be 1978 instead of the current value 1214. Many ranges has the same problem. Probably you will need to recompute all values from scratch.

I'll /try/ to find some time this next week to drill down. Currently working on some very lowlevel C work for another project.

I found that this page has not been updated in the last few days. For example, I found one factor yesterday and another today (both in the range 17.1M), but the Web page has not changed.
