You can probably wait and see the final results of P-1 before taking any definitive action on TF.

Grrr... You are still not giving me actual numbers.

Ok. Current status:

Very close. If you're lucky, P-1 will...

Well, it's possible. I too did some approximations to pick a representative B1/B2 bounds for the existing P-1 work done.

However, I don't think I'm that off. How many P-1 tests have you done, and...

Nope. It is applicable for Stage 1 only (Stage 0 is a fast form of Stage 1). Only those of us doing humongous P-1/P+1/ECM on small-ish exponents need to worry about this.

Sounds reasonable. With the older "2 tests saved" setting it would've spent more than 2x that amount.

Don't worry about reproducing the outcome of the calculator. Just set tests saved to 1, give as much memory as you can spare, and let P95 / gpuowl calculate the optimal bounds.

The real chance is more like 1 in 36, so you might find something like 60 factors. You could fall short by 15 factors in clearing this range with this P-1.

Sieving has lot of memory activities, which means there is some waiting on the CPU for memory. So this is kind of expected.
