What would help is a summary (most of this info is listed at the end of the log): Time spent on poly select (you can sum size and root, or report them separately) Time spent on sieving Time spent on linear algebra Qrange sieved (not in summary) Number of relations needed, if the first filtering pass didn't build a matrix. The relative timings of the 3 phases help me tune the target relations count if the matrix step is too long, add relations and vice versa. The Qrange helps to set Qinitial. We target a ratio of 7 to 9 for Qfinal to Qinitial. If that ratio gets too big, we get extra duplicate relations and should increase startingQ; if that ratio is too small we're missing out on speed by not sieving small Q so we should decrease startingQ.

Next up is a C140, which I ECM'd to t43.08 (yafu default). I won't have access to the nfs machine until next sunday, so if anyone else wants to try their luck with a biggerish factoring job, feel free to. If noone does I'll get to it next week.
VBCurtis: I'll get you the numbers once I get access to the machine. I remember the initial relations weren't nearly enough, there were like 45 relation increases necessary. But I'll know for sure once I get back to my machine.

I'll knock out the C140 today.

C140 done, next line has zero ECM done. Ready for jagotu to continue, if interested.

Sure, I'll move it ahead a bit :)

Next up is a C133, that I ecm'd to t40 (2557 curves @ 3M). Again, anybody feel free to knock it out now, or I'll get to it with my nfs beast on sunday.

You advanced the sequence pretty well. Thanks!

The only request is that if someone does start NFS on these, post a claim so duplicate work is minimized. Thanks to all for the effort in this.

As no one else showed interest I'm gonna keep moving the sequence myself for now :)
VBCurtis I lost the original polyselect time and used a msieve poly, but here's the rest of the stats. Code:

The sequence reached a C157 that didn't want to give under ECM.
I did a full t45 (4480@11e6) and an additional 1200@43e6. Yafu wanted to reach t48.31 (total 3821@43e6, so 2621@43e6 more than I did). As the number is out of my ballpark, I'm gonna leave it to someone's bigger powerhouse.
