Zergpool Profit Accuracy
Zergpools implementation of Yiimp seems to balance hashrate across an algorithm, so some miners are mining the most profitable, but some are mining much less profitable coins.  The share percentage is directly tied to the coin you're mining, and your payout is based on this.

I have two rigs that I have had mining to zergpool, one will sometimes show just the algorithm it is mining, the other will often show which specific coin it is mining, the functionality to keep track of the profitability for each individual coin and make switching decisions based on this seems to exist, but be inconsistent.

As such, I must raise the question, how can we be sure that with Zergpool enabled, MPM is making accurate switching decisions?
