NL 100 - How are my stats??

[KidFresh]

I just started using Poker Office.

.50/1 (9-player) @ Stars
My stats after ~1800 hands: 19% VPIP / 6% PFR / 3.0 AgrF
So far I'm +$600. (or 15 big blinds/100 hands)

I've been pretty selective at the tables I play at where VPIP is >27%.

Is my win-rate sustainable? I know the sample size is pretty small. Am I just running hot? Is my image TAG, Rock, etc.?

Your input or suggestions is appreciated! Thanks!
