7 Threadyears 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 threadyears total.
2330L needed 99 threadyears 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 threadyears 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.
