This one has a higher E (but skew should still be adjusted):

I’ve passed c5=8.3M with no flares so far. Should reach 9M within a week. Hoping for a 2+ but so far nothing over 1.75. Forward!

It does spin up a tiny bit with a triple drop in skew:

Thanks Max. Still pretty bad score but hope springs eternal.

R507 C200 polys
 

My sincere thank you to everybody who participated in polynomial selection for C200 (repunit R507 cofactor)! I collected and sent a total of 21 different polys to Kurt Beschorner yesterday, all of them were better than my original 4.163, four best were above 4.5. Kurt is test-sieving them next week. When his team decides on the best one/couple, I'll post all their parameters here. At that moment all of your critique/advice is appreciated.
Thank you again! I hope that 4.531 vs 4.163 will shorten factoring time significantly, and without all your time and effort that would never happen.
