A Couple Stats/PT Questions

[Anheg]

I've been down lately, and I was wondering if there are any glaring weaknesses in my PT stats.

Also, can anyone explain how to use the Position Stats tab?

For example, my net amounts are all positive except for the BB and SB lines (-434 and -239 respectively). Then, under Diff w/o blind they are both positive, 429 and 149. Does this mean anything important?

My Stats (1/2 limit, both full ring and 6 max:

Over about 5,500 hands (Yes, I know its small but I'm trying to catch stuff early.)

VPIP 20.01%
VPIP from SB 34.59%
Folded SB to steal 86.6%
Folded BB to steal 59.6%
Att. to steal blinds 18%
W$WSF 36.58%
Amount Won (165.39)
BB/100 (1.5)
Went to SD 32.58%
Won $ at SD 55.56%
Preflop raise 9.56%

Any other key stats necessary?
Thanks for any and all input as well.
