Your new PAP indicates an inverted track, first track ring closer to the fingers than to the thumb.  If a different driller measured the PAP, and especially if it was done on a flaring ball, it could be as simple as a difference in the determination.  First, best way to measure the PAP is on a non-flaring ball such as a plastic spare ball, and no matter what method is used to confirm the location by taking the ball to the lanes and marking the PAP location with a piece of tape, which should remain stationary for the first couple of ball rotations.  If this wasn't done by both drillers, I suspect the accuracy of one or both of the determinations.  Secondly, a strong flaring ball makes the determination difficult.  The piece of tape has to be watched very closely as soon as the ball is released because the flare will begin within the first 5' of travel.  The bowler cannot see this, the observer has to watch it.  If the PAP was simply taken from the ball's track it's no better than an estimate.

At the Powerhouse two day seminar I attended last spring, I was told that the difference between an inverted and regular track was in which finger exited last.  I don't remember for sure, but I think Jeff said that if the MF exits last the track is inverted.  --  JohnP
