Since i'm done with the earlier poly, i'll give it a go fivemack, 0-2M range.

C190 Poly
 

I'll start with 4-5M.

C193 Poly
 

Nothing better through 5M. (1.282)

this is what I have

if anyone wants to try to improve those into better polynomials

Half way through my range and I got this one:

4-6M range complete. Starting 6-7M.

almost done with my range ( last stretch will be tonight), but I got something better

1.88e-014, nice. I have a small collection of 1.7e-014 -1.79e-014 if you want to testsieve them.

Nothing better found, range done

Thanks for the F2157 work! My strategy of looking at fairly high c5 to keep the skew low is pretty clearly the wrong one, I will start at the bottom next time.

firejuggler's 1.881 sieves slightly faster than RichD's 1.900 ; the job is queued on 15e and shouldn't take all that long once the sievers get to it.
