True. But "finishing on it`s own" means they will be factored as part of the effort to find new MPs, and that will take a LOT of years to progress up the ranges until 1G. Without some dedicated...

13.65 -> 13.7.
I am P-1'ng. I won't be TF'ing these < 20M ranges, as I don't have access to a suitable (read: fast enough...) GPU.

As there seem to be no ranges lower than 10M available, I'll move to the P-1 on low exponents project. I will probably focus on under 1M. Will come here later for...

As well as 6M.
Below 100M, there are currently 87 1M ranges with less than 20,000 to go, 12 between 20,000 and 20,499 and just one with 20,500 or more. Great progress.

I tried to allocate a bit less memory (11GB instead of 11.5) and that appears to have done the trick. At least stage 2 completed initialization successfully. Let´s see how it goes.

Why are you saying it switched from AVX-512 to FMA3 FFT?
As far as I can see, upon entering stage 2 it changed the length of the FFT (and as a consequence the value of B2) but not its type.
