That page contains a few coins, but from Awesome Miner's point of view, MPH is not a source for single coin information because WhatToMine is more complete in terms of coins and information.
But for someone who is only mining with Mining Pool Hub only, then only those coins matter. And it could be argued that MPH rating for BTC/GH/Day for it's own coin pools will be more accurate than WTM because it can account for it's own transaction fees and because it will be based on it's own actual performance.
It might be a variantion of one or a few percent, but even if MPH calculates given their previous block finding luck in mind, that's never an indication of current or future profits anyway. I do understand your point here, but for the moment, WhatToMine will be the main source for coin information. If more people requires this feature, I will of course been considered for future development.
