My thoughts on POI shift is that it is a clumsy indicator of quality. The 'free-bore boost' phenomenon almost guarantees a shift in POI. What is an indicator of quality is the size of the group with and without the suppressor attached. If the group is no bigger with the suppressor fitted then that is a pretty good indicator of lack of yaw from either run-out or turbulence introduced by the can. By lack of yaw I mean there is either no yaw introduced by the can or minimal yaw that has corrected itself from spin.
For those with suppressors one way to eliminate POI shift is to always shoot with the can attached. Zero with the can and shoot with it, always attached. POI shift becomes moot.
