Been running cgminer and my avg hashing rate is 2.833Mh/s but combined accepted/rejected hashrate per your site seems to be hovering between 2350 and 2500Mh/s.  I'm fairly new to mining but having tried out Middlecoin, Cleverming and WafflePool for a couple days each, they all virtually nailed it.  Any suggestions as to why I'm coming in below and/or what to do about it?
