58.3M CPU-seconds of sieving gave me this:

Probably needs a bit more sieving. Poly score was similar to the last two jobs, so 31/31 seems to be a little slower than 31/32, especially when you account for the more efficient qmin on this job.

Worth trying mfb0 = 59 (this was with 58), or would that be unlikely to make a difference?

(Also a c168 Homogeneous Cunningham has popped up - what params would you suggest if I decide to do that next?)
