Even 30% is a bit too loose for me to justify playing. My worse days are all signified by my VP$IP raising to more than about 20%. Half the time this is just trying to play a hand when cards have been scarce. I start dropping down from my normal 23 handed starting requirements and that's when I start getting whupped.
Right now I am about 17% average VP$IP, with a PFR of about 6%. Ideally I'd like to raise both to about 20% and 10% respectively, but that will come with time.
