I've done about 2000 curves with B1=11e6, and three P+1 runs with B1=1e9, B2=1e14.

I've started polynomial selection.

Probably need about 18000 more ecm curves @ B1=11e7 before sieving.

I consolidated the counts so far. I've also set up to run some curves @ 43M.

Looks like I can manage close to 1000 curves a day @ 43M....so 1000 so far.
