This is sort-of a BOINC question; if there's a better place to put it, please let me know.

I've noticed looking in BOINC that my recent average credit (RAC) has absolutely cratered in the last ~12 hours. At 00:00 UTC on 10 April, BOINC reported my RAC at just over 200k. Since then (~16 hours at the time of this post), BOINC reports that I've earned slightly over 1 million points, but my RAC has dropped from 200k to about 130k.

I'm not sure how this is even possible! The BOINC Wiki says that if you earn no new points, RAC follows an exponential decay, dropping by 50% per week. Yet, somehow, my RAC has dropped by about a third in about twelve hours, all while my devices have continued to turn in work (and this ignores that even the RAC of 200k is still well below what my devices are going...).


Anyone else seeing this sort of thing?

EDIT: And down another 15k off of the RAC (10%) in about 50 minutes. Looks like it might end up negative at this rate
