indicative of leak?

[graarrg]

I was poking around in my Misc Stats bar in PTO and I saw something that looked horrendous. Under "Known Final Hand summary" I had a net loss of $319 for two pair (relative to a total net gain of $330). However, when I checked the "show hands that were not folded" box I was thankfully in the green. Is there any way I can analyze this data for a leak?

I'm under the impression that it doesn't mean much considering it's the net loss of folded hands.. but one can never be sure.

Thanks!

(Fyi, I play .5/1 and am at approximately 6.5k hands)
