Correct my logic if required:

I looked at the current and new B1/B2.
For example 400K/400K to 600K/100M.

That was early on before I understood what I was doing.
I had a couple slow PCs doing ECM in the under 10M Ranges.

Most of the GhzDays are from my 2080Ti GPU.
I does over 4,500 per day.

Thanks

And it seems the TBD value of B2 ... at least for this 1 PC ... is brilliant now.
The value chosen is 256xB1; which for this PC gave very similar Stage 1 and Stage 2 times.

Considering my Stage 1 time dropped from 14 to 10 I assume a good part of it was AVX ... umm I mean AVX-512.

Good questions.
1. Correct .... we are at the mercy of poor P-1. However as the required TF bit level increases this will matter less.

According to my calculations that percentage should give you 78 factors....well done.
I like your plan ... I'd start with that for the current B1=B2 and hope for about half the factors.

If you'd like a hard range on the lower end there is 10.4 or 10.7.
Anonymous may be there in a couple months with one more bit of TF.
Or you can claim one of these range and Chris will release it...

I ASS-umed because my PC supports AVX-512 but I turned it off in local.txt.

Stage 1 is 10 Mins with AVX512 and 14 Mins with FMA3

Because Stage 2 is several times faster than it used to be the optimal B2 is a much higher multiple of B1.
This will...
