What is my huge leak?

As I'm sure all the other posters told you (I didn't look yet) 5k hands isn't really enought to talk about stats. But I have two recommendations:

1) You really really do need to PFR more. Read SSHE.
2) Your agression seems really low. Read SSHE.

It looks like your won $ WSF is low, but that could be because you aren't agressive enough or just because 5k hands is meaningless.
