Like right now cgminer says 5025MH/s and the dashboard on 50btc says my 60 minute average is 4119 with 3452 shares earned in the last 60 min.  I know how they say to go by the miner app speed but if I really was doing 5GH/s my 60 min shares would be between 4100-4200.  So it seems like something's getting lost between me and them.
