My hashrate over the last 8 hours has been 2.15 when I have 3 rigs totaling 5.9Mh/s.  They are all running, pumping out heat, and supposedly connected to middlecoin.com:3333.  I have been on MC stably for over a month with the same cgminer.bat file, so I know my public address and configurations are correct. 

Thoughts??
