As noted above, past record cannot determine the pools future (other than to show the quality of their connection ie low orphan rates). A pool that maybe have solved 20 blocks in the last 3 hours may get 0 blocks for the next 3 hours - it happens quite frequently.
But if there was a page monitoring for example: middlecoin mines only cat, doge, 42, etc and similar list for other pools, you should be able to see how efficiently every pool transfers altcoins to bitcoins etc:) I know it's a quite unpredictable thing but what I was asking is if is out there any page like
