This is not the first time I have seen someone question a product with unfounded testing. My CPS does exactly what it says it does. I do not uniform pockets unless they are grossly undersized, and even then I question doing so. The pocket bottom is concave for a reason, making it flat just for something to do has shown over the pressure trace to change ignition start pressure. The CPS is great because I can measure actual crush, not just how far below flush of the case head.
