Just to clarify, I think that the tracker must reset your stats (on a particular torrent) at other times besides when your client restarts. I'll have a torrent seeding for weeks and I can see that the stats on a particular torrent will reset, even though I have not restarted my client or computer that entire time. I suspect (just guessing here), that if you don't connect to another peer for some period of time, your stats start over.
