For C193_194xx723_13, the generated WUs cover the 6M36M range, but the management form suggests an upper bound of 40M. I'll raise it to at least 38M.

While we are talking Q ranges, the following might be considered.
C221_691xx579_7 could use just a touch. The sweet spot seems to be about 228236M for a 31bit job. A matrix can be built at TD=110 which requires just under a week, instead of 1.52.0 weeks for something must less. Likewise, C169_203xx091_19 C217_69655517_29 C172_115xx057_17 could use a little bit more to get into that range. I'm not too familiar with 32bit jobs but it seems 450460M might be the sweet spot. Therefore, C176_M127_k24 could use a little bit more also.

Data points, all 32LP: GNFS 170 275M relations 9.9M matrix (run on 15e J 13, so 14.5e) GNFS 166 274M relations 8.9M matrix TD 104 GNFS 165 265M relations 10.3M matrix TD 96 I sieved these all myself, so I used fewer relations and lower TD than I would for gridsieved work. I don't think more than 25% oversieving is needed to build TD 120+ matrices. Data points for 15e/33LP: GNFS 172 529M relations 9.0M matrix TD 104 GNFS 175 556M relations 10.7M matrix TD 112 Two points is not a trend, particularly since I used different TDs, but based on these I'm using 510M + 10M* (GNFS size 170) for 15e/33 tasks. I'm running GNFS 179 right now, but using 15f and 16f for some of the sieving so the number of relations won't provide useful data. EDIT: That C176 didn't have good parameters, and the sieving has already run to Q=750M. That suggests duplicate rate will be lousy too, but with Q already over twice the lim's we may collectively just have to eat the large matrix awaiting us (or sieve a little with 15e or 16e at the low end of Qrange). I'll have time to take it on in 10 days or so if nobody jumps before then. Last fiddled with by VBCurtis on 20180531 at 16:57

* I have adjusted the ranges for C169_203xx091_19 and C172_115xx057_17 to match the ending Q values currently recommended by the management page. The latter will probably have to be adjusted again.
* the range for C217_69655517_29 matched the recommended range, but sieving hadn't reached 90% yet, and the grid's starving, so I expanded the range by 5M. * the range for C221_691xx579_7 slightly exceeds the recommended range, and there were zero pending WUs, so I've let that sieving job RIP, and I've reserved it for postprocessing, as I can't see another reservation in this topic. Technically, the recommendations made by the management page could be adjusted if enough people agree that this is the right thing to do, and we can borrow a bit of time from Greg. Tom ? Others ?

I don't have enough data points for a recommendation. This is the job that recently came to mind.

Yes, raw relations under 14e (with its higher dup rate than 15e). I really really think 32LP should be used more instead of 31LP, with much lower than 400M relations targeted.
