Let me be clear - I'm making no accusations here. I'm just mighty puzzled. A user that typically turns in about 700 cobblestones a day (RAC), give or take, from 17 hosts, only a few of which have turned in anything recently suddenly got 28,677 credits in one day.

Would a very large cache being uploaded all at once from several computers be granted so much instantly? I suppose if they were the last to upload on all of the work units to achieve quorum it would have that effect.

Any of you gurus have a better idea that I do?

Again, I'm making no accusations here. Those of you that know me know it's not in my character to do so.

We do have a few crunchers (and I do NOT know if this person is one of them) that work at places where they occasionally burn in a few hundred PCs for a month or so. This can generate a huge increase in their score for that month. Then it is back to their normal half dozen or so computers that they control - so it drops again.

We also have a few crunchers that have made arrangements with places like cyber cafes.

Just the other day there was a user with a discrepancy in his credit totals who was missing about 30K credits. His credits were restored. It wasn't the same user but could be a similar case perhaps.

Edit: in fact his graph looks very similar http://www.boincstats.com/stats/user_graph.php?pr=sah&id=21530

Thanks for the feedback, all. Since I'm not here as frequently as I used to be I guess I missed the issue the other day. I hate being a double-threader.

Ciao
