Manager=v5.2.13, just installed BOINC a few days ago.
I processed over 600 units for SETI before suspending work on the project. My user average and total for SETI still shows as increasing. The Days does show -6,-5,-4, then nothing to the end, but it's not flatlining, it's still shows increasing per day. For Predictor, in 4 days I achieved a user total of about 350 units, then in the last day it shows a marked decrease in the user total, even though Predictor is process LOTS of transactions. The user average is leveling off reasonably at about 50 (proving the total should be increasing). I'm not sure I understand what the stats are for WCG, it was flatlined for a couple days and then jumped to about 8/day. Maybe they were down?

I'm reporting these issues to better understand them and maybe to point out manager issues as well. Please feel free to point me to RTFM if required.

Thanks!

After you stop returning work, you've got results waiting for a quorum to complete. Until that happens, the work doesn't get validated and you don't get credit. It can take several days, in some cases longer for that credit to get applied. After a while, though, that'll stop and you'll flatline.

For Predictor, I'd suggest going to your account on their site and see what's being shown for your results. Credit going down isn't usual, are you sure you weren't looking at the average instead of the total? I don't know anything about WCG, not attached there, again check their site for news on outages or other unusual occurrances. Timing may also be a factor in getting credit there.

While this answer is correct I do not think it applies in this case. If the project is suspended then it will not be doing scheduler RPCs. If it is not doing scheduler RPCs then the graph will not change. The -x days will refer to the number of days since the last RPC. Try updating the project and see if that changes your graph.
