cownoise: skew 726799.19110 murphy-E 1.29348321e-15

Edit: Next attempt will be 1.05M to 11M with incr=4620, nq=46656

Edit2: deg 6 scores on the C207 had to be about 20% higher to get the same sieve performance as a deg 5; so this poly (before spin) may perform similar to the 1.05-1.1 deg 5 polys posted previously. This is *not* a sign to move all our search to deg 6! One hopes that if we keep finding 1.09's, Max will spin one to 1.20ish and that will sieve better than a 1.3x or low 1.4 deg 6.

This hit came from the best-scoring poly after size-opt.
I'm taking a break from this poly select for some time; hopefully we'll have another good deg 5 candidate or two, and Max will stop by to try some spin.
