I'm playing the 0.2 full ring tables on PS trying to learn the game. At the moment my stats are

Hands: 1508, $won: $11.39, BB/100: 18.88, VP$IP: 30.31, PFR%: 7.76 W$SD: 43.36

Is this good bad or indifferent? What the hell does BB/100 mean anyway? Any other stats you think I should be looking at?

Interestingly (to me anyway) I am losing money on the button where I would expect to do the best, and I'm losing a ton of money in the BB. The rest are all positive. I guess my hand sample is very small though. Any help appreciated
