I have changed the cutoff points:
20% = up to 20M (prev: 10M)
15% = 20M-50M (prev: 10M-20M)
10% = >50M (prev: >20M)

edit: this roughly triples the number of exponents tracked in that table from...

I have put a very rough public-facing report. With no graphs or controls of any kind. But you can choose between plaintext and really-plaintext. :smile:

I have updated the curve count for 35..65 from your ECM page. I didn't follow from what you posted how to extend my lookup table to 80 digits (both bounds and curve count).

That part is fixed -- if the factor splitting fails for some reason then there should now both be a fatal-error notification on screen, and an admin alert to me.

I'm not entirely sure, but it's something to do with it being a composite factor. For some reason the initial splitting of the composite factor failed, but seems to succeed on retry. I have added...

If you have so little RAM available, it would be better to just have one worker with 6 threads. If you try to run more than one P-1 at a time, Prime95 will have to pick unnecessarily low bounds.

Presumably ProofPower is normally auto-selected based on available disk space, but you're telling it to ignore available disk space and use the ProofPower you explicitly set.
