I use stats.hashco.ws to gather my stats for hashcows so if they're incorrect so am PoolPickers.
FYI. For 48hrs mining on hashcows with ~1.1MHs has gotten me 0.0047 BTC (unex, exchanged and paidout.). Not exactly matching what they claim....
Perhaps you should add a disclaimer to your poolpicker page then, it is gettings quoted all over but none of the stats you report agree with what I'm seeing from load balancing over those pools.
These two comments on a recent Reddit thread should help clarify.

http://stats.hashco.ws/en/profit) is derived from actual BTC paid out each day, however, this payout doesn't necessarily reflect mining conditions that very same day, as it is often a combination of the result of many rounds from previous days. The stats on the other pages (like
http://stats.hashco.ws/en/calc) give more of a snapshot of how Hashco.ws is mining right now, based on immediate round stats.
edit: p.s. didn't mean to invade a middlecoin thread, hadn't realised where I was I posted after somebody directly linked to it.
