(Did you know that you can take notes while playing in a live game in Las Vegas? This is basically the same thing that PokerTracker does, except we automate it for you). this is the same thing we humans do instinctively when playing live. We regularly admit that the stats are just a mathematical representation of memory, they do not really tell you how your opponent is playing, but the use of multiple stats together can help you create an opponent profile to estimate how your opponent might be playing. PokerTracker makes the online experience more like a live experience through the creation of stats.
Human beings are not programed to remember screen names, which makes playing online much more complicated, it requires frequent note taking. Human beings are programed to remember other humans and in some ways their their action, that is natural. Every player has a built in tracking system when they play live, you naturally and instinctively track your opponents and estimate their ranges based on frequency of actions.
