Thats not correct, you must also account for the times where the BB is walked. To see a comparative analysis of PT4's VPIP calculations methods which compensates for walks vs the old way which did not compensate for walks use PokerTracker's scatter graph. Use VPP in the X axis, and VPIP Legacy Version (PT3's method) on the Y Axis. We advise a sample size of 1,000 hands or greater for accuracy, but samples of 500 hands or less may start to converge... depends on the aggressiveness of the games you play in typically.
It is possible to have a higher PFR than VPIP, but these situations are rare and usually only occur when the sample size is small.
