SSH Tight PF Guidelines and VPIP

[Link774]

After using SSH's Loose PF guidelines for a little while, I got PokerTracker and noticed that my VPIP was around 21. Then I also noticed that I was getting more like 4-5 players (Paradise .25/.50) seeing the flop, as opposed to the 6+ that the Loose guidelines recommend. Thus, I switched to the Tight guidelines, to bring my VPIP into the Tight range for Bison's autorate (its now 17). However, recently I have been seeing posts saying that 20+ VPIP is acceptable, while I am also seeing posts saying that Loose tables are extremely rare online. Should I:

A) Screw the PSF statistic and use the loose guidlines
B) Screw the people who advocate 20+ VPIP and use the tight guidlines
C) Blend the loose and tight guidlines based on how I feel at the moment about the table

You get the idea. Discuss! Thanks!

P.S. Note that I play on Paradise, which I have heard is tighter than Party, so if you want to tell me that you play on Party and you're raking it in with VPIP 25, I don't really know how applicable that'll be to my situation. And no, I won't switch.
