I have just started mining with you yesterday.  I noticed that after I added 2x more 5850's to my system that the Worker Speed reported on your site is now not consistent (about 50-60%) with what is displayed when running Diablo Miner.  Just wondering why this is happening, or if my Miner needs tweaking.

Diablo Displays ~ 866 mH/sec and your site hovers around 410-420 mH/sec
the command line is using -v 2 -w 128 as this results in the highest speed.
could the -w 128 be causing this?
Just wondering if the issue is me or the site?
