I'll let You know when I'll be able to estimate the 'gain' in CPU hours, but I'm sure
that it will be significant.

Roughly it will be 10% on sieve and 40 CPU/h for poly, which makes 1,5 week (as Your's number). Many thanks VBCurtis !

I'll start with 8-10M and pretty tight stage1 settings.
I'll also play with CADO poly select a bit.

I finished 2.5-3M with nothing better found. Now working 3-4M then I’m out. Will probably take 12+ days to complete on my slow hardware.

I ran it through msieve to get a poly score.
Poly select settings, for those curious:
admin 12600 admax 450000 P = 4000000 root-opt on the top 40 hits, with rootopt effort set to 25.
Next time the big CADO box is idle, I'll run 450k-1M.
I think we should strive for 1.6e-14, and be happy (I mean, quit) if anyone finds a 1.65.
