What stats do you track? What would you like to track?

[Strumey]

I am trying to put together a list of stats I want to track on my game. Here is what I thought of so far. Anyone have any others I should look at? Are there any fun stats that I havent thought of that may not have much value, but might be fun to know?
Hands Played
% of flops seen when having BB
% of flops seen when having SB
% of flops seen from all other positions

% of hands won on the flop
% of hands won on the turn
% of hands won on river (showdown)
