Well put! The grip is explained by many pros in many ways. Kinda got to put your time in, apply a few different techniques and only time will tell you what works best for you. Lots of dry fire, mixing in dummy rounds in random order in live fire practice, etc. Are good ways to keep you honest. Good sight focus also helps, I even see Olympic air gun shooters use plugs and muffs to keep sound out of the equation. Lots of areas to work on in getting to where you properly manipulate the trigger. Trial & error is the basic approach to this game. Rob Vogel uses an entirely different method than Rob Leatham, but both are excellent shooters.
