That is fine. If you have to re-start the poly selection, though, you'll need to specify those bounds to something which was not already touched. Otherwise, you don't need to set them.

did only 296 ecm @ 3e6 since batalov finished i guess i'll post poly in the morn and we start? with the lack of response and sudden interest in aliquot over einstein@home, im running 2000 11e6 curves :) hopefully they will be done in the morn.

c125 is a bit small for a team job I think.

Indeed, that's 4 days or less of work for a dual-core computer.
Nowadays, GNFS 154-155 (512-bit integers) are doable by a single dual-core desktop computer in a couple months of calendar time.

right, who is going to do it? not me, im doing postproc for something else sounds like. I'll post my poly's when I get back.
