The top score for a C179 is 1.226e-13. I will report anything above 1e-13.

Eta: Best poly so far had a very unimpressive 8-handle.

The best in the 4M range was 8.0. Continuing with 5M.

Best poly I found in 0-2M per msieve-GPU. Maybe it can be spun, but likely nowhere near enough.

Searching 2-4M next. Also giving CADO a try.

The essential change to default params for CADO poly searches is to use nq=5^6 = 15625, rather than default 5^5 = 3125.
It's possible 5^7 = 78125 is better yet, I haven't experimented enough yet.
Edit: Search time is linear in nq, so this will take 5x longer than default. Reducing admax is wise, but user discretion.

Currently searching 2-4M, should have results this weekend.

Shifting my focus to CADO - it’s searching now. Hoping to get a poly by this weekend, as the search space was limited < 200K. Kind of curious to see how CADO compares to msieve on a C179. Hoping to try a few variations on a couple of the parameters.

None of the 4 polys above seems to spin up, sorry.
