Everytime I checked them out just didnt seem right to me.
Pokeredge,Pokerratings,Sharkscope,and all that stuff I personally stay .
What's not 'right' about them? There are other sites online as well and you're able to set filters on them to see exactly what kind of results a player has (ie.,... you say he sucked at first but now he owns.... so you can run 'full stats', last 30day, last 90, or from one specific date to another).
One big way this can help is,... if a player is a LAG and has horrible stats. we can then start making quite a few assumptions about them based on their betting patterns (just a simple example but there are many ways in which this stuff can be beneficial).
As far as PokerEdge goes, how couldn't that be helpful? (obv. is otherwise it wouldn't be illegal to use it).
