So I was working on my stats site and got some history comparison graphs going on. Then when I looked at one of them I saw something very curious...
<a href="http://macg.no-ip.info:5520/boinc/tgraphs.php?proj=cpdn&amp;teamid=45">http://macg.no-ip.info:5520/boinc/tgraphs.php?proj=cpdn&amp;teamid=45</a>
It seams the statsfreakz team LOST a bunch of credits about 12 days ago. Did I miss something here? does BOINC have negative work units? :) Or was this just a byproduct of the credit problems that were going on a while back? I see there is a corrosponding increase in credit 26 days ago. Can anyone else verify this or is my database corrupted or did the aliens from seti@home use a TBoIP (Tractor Beam over IP) to mess with me?

Checking them against my team, look at the weird histogram for Ubersearch: http://macg.no-ip.info:5520/boinc/tgraphs.php?proj=cpdn&amp;teamid=12

This was explained by Carl in one of the other threads, though I cant explain exactly which one.

In short (my memory is vague now that its been a while), Carl had to "update" the CPDN database, as there was an error of some kind which mean that certain individuals had been given too much credit for certain work units. The update simply recalculated what their total was suppose to be.

For the vast majority of users there was no change, for some they went BACKWARDS on that day (all be it backwards to their correct total instead of being artificially inflated)

I believe it was only beta accounts that were affected.
