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.
So far every range from 86.4 to 107.9 has cleared. As noted...

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.
I couldn't think of another reason for the change...not that there isn't.

Stage 1 is 10 Mins with AVX512 and 14 Mins with FMA3
Crazy idea ... can I run Stage 1 with AVX512 and Stage 2 with FMA3?
Probably not worth the effort for anyone.
I'll wait for the AVX512 version...

Pondering 30.8 with respect to this project.

George in 30.8 is working on determining the best B1/B2 for this new version.
Because Stage 2 is several times faster than it used to be the optimal B2 is a much higher multiple of B1.
This will...

I've added 20.3 and 20.5 to the ToDo list on Post #1

They are only TF'd to 73 bits but each range only needs 19 more factors.

If you choose to TF them to 74 they will likely clear.
If you choose to P-1 them with modest bounds they will also clear.
