Still nothing in the expected range or better than previously posted. Taking 1.5M-2M.

It is getting a little better. Continuing on down to zero.

Really good poly. What on earth made you look above 1e9 for it?
I am "generally" getting better results the lower I go.
Though nothing better then my last post and I only have the range 2-300k to go.
It should finish within 24 hours.

It was an experiment with a very smooth leading coefficient.

I have completed the range up through 6M with nothing better to report. Giving up for now.

I just got my CUDA rig working again; I'll start at 10M with a low stage1norm (meaning I'll fly through a bunch of a1's). I'll report my best after two GPU-days and decide then whether to continue.

4.5 GPU-days on a 750ti got me 29 hits below 2e25, and a best poly score of 1.569e-14. Not competitive. I -npr'ed hits 5e25 or better.
I ran from 10M to ~15.4M with stage1norm just under 3e27.
This ends my effort on this number.

So is Gimarel's poly the clear winner? If so I'll do some test sieving and propose it for the 15e queue.
