Don't focus so much on the number. The main point here is that he used a house ball to get your numbers. Maybe you have a really generic hand so it worked out for you...But I know that for people like me who require specific, unusual pitches (as well as a really ovaled thumb hole) it would never work. I've thrown house balls that "seem" like they fit my hand, and it's not even close to how I normally throw the ball. But it may not be so in your case and the PAP could be close to the same. However, the main point to this is questioning the method. If a driller uses a method that *can* be wrong, then there's something, well, wrong with that.
