I may have posted this on PF: video analysis software has been used in technical training in other disciplines for the decades. My entire family has done late Vic Braden's tennis strokes video analysis years ago. Video imagery is always an adjunct, first measure the performance, then identify weaknesses, then see if the video can identify cause-effect relationships, etc. I would argue that there's no perfect or ideal shooting form, or grip, or presentation. Some aspects are agreed on, and some are highly variable. People do great with press out and present-pause-press. People do great with pressing a trigger with a tip and a crease. People do great with aligning the gun with the V, and without. Some need to lean into a gun, others produce .18 splits while standing seemingly upright. I can absolutely guarantee that pointing support hand thumb at a target is counterproductive for many shooters. Some still put support hand index finger on that trigger guard, or go Vogelesque. A big one - what you do at speed is very different from what you do at a sedate pace.
That is my long winded way of saying that I don't get how technical teaching can occur without measuring technical performance first, just on a form factor. Obviously, I wasn't there, maybe I would've gotten it better if I was, but just reading it, it is hard for me to buy into it.
Maybe yes, maybe no. I took swimming lessons from a pro this summer, that little torturer made me swim some quarter of a kilometer to evaluate my form. Hawthorne effect is a classic research bias, you do things differently when you are observed. Multiple sampling or making people tired are some of the ways of working around it.
