Since they only keep track of flops saw its hard to gauge what your vpip is. The only stat on there that is semi useful is won at showdown. But i mean its such a small sample even then its hard to really read too much into it. If you're saw flops % is under 20 and your won at showdown is reasonable you're probably not spewing too bad. I honestly wouldn't worry about stats until you manage to get poker tracker working and even then it shouldn't be your main concern.
