If u can use your inteligent proxy to throw enough KH to small coin's, you can take advantage of them too while big multipool's can't. Big pools throws all of their mining power to coin, therefore they cannot mine small coins who has very big profitability.

I suggest that add more coins to your monitor system specially those coins that big multipools cant mine because of their big mining power.

and add more stats please. specially BTC/Mh/Day history.
