The three best spun polys are below, all above 9e13 (22% better). All are in the format c4,c3,c2,c1,c0,Y1,Y0. All need testsieving of course. A full list is attached in a text file. Code:

It's so easily scalable to c5 and c6! Code:
# modify the following two values fields = "c4,c3,c2,c1,c0,y1,y0" entries = """ ... I hope you don't mind us advertising it a bit on your behalf. Thank you so much, swishzzz!

The sieving goes on... 21,608,085/22,162,816
I was hoping the estimation was good, because I got a similar value of 17,000,000 with the function that yafu uses. Well, as long as it won't take longer than a comparable GNFS run, I'm fine. :D The rels/q are already down to 1100 rels / 10000 q though.

As for line 161, the c326 shed a small prime to become a c298 which has had t50 ECM. I'm curently ECMing the c328 a bit. . .
