The problem with the PokerStars
stats is that it will not give you anyhwere near an accurate VPIP (Voluntarily put Money In
It counts the times you are in the BB and can check see a flop. It also will not count the times where you call/raise preflop and then end up folding to a reraise.
That said, 30-40% flops seen would still be considered pretty loose. When I'm running tracking software (Pokertracker for me) my VPIP will be around 15%...this corresponds for maybe 20% on the Pokerstars stats.
Whether you are passive or aggresive depends on the % of times you raise as opposed to calling preflop. If you hear someone say they are 14/12 that means their VPIP is 14% and their preflop raise is 12%. This would be considered TAG.
When you start getting up around 30% VPIP you are playing loose by most people's definitions...even though it might feel tight compared to what you were doing before.
Best advice is to get some tracking software...it will do wonders for your game by giving you a better idea of what kind of player you are. You will find the hand analyses on this site much more helpful when you know your own stats and can compare them to how other successful members play.
