Seriously, it should not matter what your vpip is. It's very dependant on who sits at your table, game structure, and payout structure.
If you're in a table full of nits, you loosen up your vpip/hand ranges and start stealing, bullying, etc.
If you're in a table full of spewtards and loose aggro fishes, you're gonna have to tighten up your hand ranges and ship your chips in when your
equity is very good, and hopefully they pay you off.
If you're on bubble play with a huge stack, you're gonna have to loosen up and start bullying a lot.
If you're middle stack on bubble play of mtt and some jackass goes all-in against you, you're gonna have to tighten up lot of starting hands.
Lot of these situations and more get added up and then get averaged out. Just because some regular or some professional has vpip of 25% don't mean you gotta play 25% of the time.
