7 Thread-years to produce 70M relations. I estimate Greg will use 1200M or so raw relations for this job; if we guess that CADO would be half as fast at higher Q than at Q=20M, that's around 250 thread-years total.

2330L needed 99 thread-years for C207; if the above estimate is correct, 10 digits more difficult but only 2.5x longer is a nice ratio!

Then again, I had estimated 65 thread-years for the c207 when it began, which means this C217 estimate is just under 4x longer than the C207 estimate- just as one would expect for 10 digits tougher.

We're at Q=29.5M now; I'll shut down the server this afternoon.
