Nice work, Max!
I'll test-sieve a few of these sometime this week; if the 2.2 sieves well, I think we have a winner. Once I have some stats on estimated Q-ranges, we can query fivemack and/or frmky to determine if this should be placed on 16e or 15e queue. This would be a record for GGNFS 15e, but such a record comes with a matrix more difficult than it would be on 16e.

On the GPU search, I'll complete 20M-36M by 1 June.

I should be done with 8-10M this week. Maybe I’ll get a flare. But I’ll stop there unless further searching is necessary.

This would be a gargantuan 15e job!

Any ideas on the next target for poly searching? I’ve got three to choose from: C178-C184. They seem embarrassingly easy after this C205. But those are just suggestions.

I'll have at least two more different 2.2s very soon, maybe today, my CADO is still brewing. They have high skews, but I might be able to scale them into lower skew/slightly lower E.

The correct skew and E for the poly above:
[code]
skew: 1278101.55748
E: 4.85554836e-14
[/code]It's better than the best C184. Great job, vebis!
I would suggest a baseline of 5e-14, than with some luck there is a chance to spin it into 6e-14.

Ok I’ll run this over the range 1 < c5 < 2M, opening up the S1 and S2 max norms a bit more to potentially catch more/better flares. Looking for at least 5e-14.
