I apologize in advance if this is offtopic (and taking suggestions on where to move it if it is).
I was wondering about the inner workings of middlecoin.

If I understand this correctly, it switches to mining the most profitable coin by pointing its hashpower to one of the altcoin pools? Is there any way of knowing which pools those are?

Also, most alt pools (from what I can tell) are either PPS and take a percentage, or are PPLNS with 0%. So in case of a PPS alt pool are we effectively paying a compounded percentage (both to the altcoin pool and middlecoin)? Does PPLNS average out or is it less profitable than PPS for pool switching? If we are mining on PPLNS altcoin pools then we have a delay in receiving shares, so no immediate trading can occur?
