With most pools I point my miners at, I am able to get a normal average of 5.8 Mh/s in total.

When I am mining middlecoin, my instantaneous and average hashrate is reduced, across all miners, all cards, as I type this my total average hashrate on middlecoin is 5.4 Mh/s.

Is there anything that I can change in my setup, or is this completely in the hands of middlecoin?
I like mining on middlecoin, it reduces the labor involved in mining altcoins to trade for BTC, but if I'm losing 400kh/s on top of the pool fee I should probably switch to another pool.
