Approx. 8.2M thread-seconds for this second run, 11M total.

The score from the first poly in this post is about the expected record score for a C215, if we use previous records and extrapolate from C210-211-212 records. However, the more recent CADO-team records for RSA-210 (1.49e-15) and RSA-220 (3.88e-16) suggest something like 7.6e-16 for C215 is possible. So, maybe more like a record C216 poly- except this is a C217. Anyway, this is a good poly, and Max should see if any improvement is possible. I am pausing poly search for a bit, so that others might join in the fun. Anyone interested in a CADO run might choose: deg 6, nq = 46656, admin 2e6, incr 420, P = 12000000 to 14000000; admax is a matter of how many CPU-hours you wish to spend. Each 1M interval is roughly 5M hyper-thread-seconds (on 2.6ghz ivy bridge).
