If you set skew to 410M, do you get the same 40 relations? A "no" would conclusively reject my claim.

I think you are getting confused with the way that GGNFS 15e internally adjusts alim/rlim down to Q0 (IE if you do a f 20000000, it will sieve with alim=20000000 if the value in the poly file is larger than that)

Thank you for doing the footwork to confirm my misunderstanding. Your explanation is the best I have, until I get around to perusing some of the places where esoteric GGNFS discussions have taken place 'round here.

So, I'm moving my CADO search to deg 5 next time I have some free cycles; I expect a 9e16 deg 5 to be faster than either of my deg 6 polys here. Last fiddled with by VBCurtis on 20190916 at 02:58

Gimarel found quite a few good polys for 2330M using msieve (admittedly, with his secretsauce using multiples of 120120 or 210210 I forget which as leading coefficients).
I'd start somewhere like 50 million if I were using msieve, and if I had a functioning CUDA install I'd be using msieve in addition to CADO.

My best polys so far. I hope to get above 1e15.

Well sure enough, when I returned home from my travels msieveGPU had not found anything useful. I’m pulling the plug on my search temporarily, but I will likely later take up the suggestion by VBCurtis to search a higher range, e.g. c5>50M. And I must play with CADO poly search  I don’t have much experience with CADO but it is very powerful.
