I just noticed that this result's stderr.txt output didn't quite match up to that of other sieving workunits I've crunched--whereas all the others said either "factors file found" or "factors file not found" at the end of their stderr.txt, the one linked to above didn't. Is this a potential bug?

Also, I've noticed that the aforementioned WU and all the others I've received to crunch after it have had a quorum of 1, whereas before all sieving workunits had a quorum of 2; is this a change made to all the sieving workunits in general, or just an error made with those workunits? I know that over at Riesel Sieve I heard that since they can validate sieve results quickly and easily without doublechecking them, they only needed a quorum of 1 (especially since they use fixed credit), but I figured I'd ask here anyway in case it's different.

And while I'm at it, here's another question about the new sieving workunits: I've noticed that the workunit that I had linked to at the beginning of this post was granted more than half a credit more than the previous sieving workunits that I'd crunched. Is this intentional? It looks like the sieving app here has fixed credits (IMO a good thing since it is just about the only foolproof way to stop cheating), so the only cause I can imagine for this is a raise of the fixed credit by the admins; is this the case? (FYI, all of the credits I've gotten for sieve workunits have been more than my client's claim, anyway.)

Um, it does say "Factors file not found"...

Quorum has been reduced to 1 exactly for the reason you mentioned - it's easy to verify factors, and we give fixed credit anyway. The fixed credit may be adjusted now and then; changing values are intentional.

That's odd, it didn't when I first looked at it, even though I did so more than once, but now it seems fine. Oh well, as long as it's fine now. :-)

I see. I guess I shouldn't have been surprised, considering that I asked the same question when TPS workunits went from 1.25 to 1.32 over the course of a few days. ;-) I'm not complaining, though, since the fixed credits here (and mostly at every other fixed-credit project I participate in, too) have always been consistently more than my client's claim. :-)
