I'm new to btcguild (a tentative move from another mining team) and trying to understand why the number of shares that I show solved on my desktop, the pool block history and the my account page don't add up.

Right now, the "my account" page shows 43 total shares solved, of which 2 are from "this round". This suggests that I should have 41 shares from previous rounds. When I go to "block statistics" and add up "my shares", I get a total of 23 (including from unconfirmed blocks). Am I misunderstanding something here?
