Best ways to identify leaks in poker tracker

[Marc Desjardins]

Hi, I am not sure this is the right forum, so please redirect me to the right place or to previous discussions if needed.

I play 0.50/1.00$ on Empire and after about 20k hands, I've finally reached the bankroll to move up to 1$/2$, but before I do, I just want to be sure my game is top notch. Any advices on what to look at to plug hard to find leaks. I know the obvious stats in PT and they are fine:

V$IP: 21.92
V$SB: 40.38
PFR: 6.14
AGG: 1.61
BB/100: 2.89

But those stats include my first month of play (about 2k hands) where I had no idea what I was doing and a very bad downswing of about 200BB over 7 days last november.

Here are my stats for the last 8k hands (after the downswing)

V$IP: 18.32
V$SB: 34.90
PFR: 7.99
AGG: 2.35
BB/100: 4.87

So, I think my stats are fine, but I just want to be sure I have no leaks that are going unoticed at the current level but might kill me at the higher level.

Any tips on what to look for in the hand histories? Using the hand filters maybe?

Thanks for any advice you might have
