OK, we're on a different page. I used to read the Ayoob files every month in American Handgunner. A play by play of various shoot outs, interviews with the good guy, the aftermath & repercussions. I don't know how long he was/is with AH but I had a subscription for 30 years. That's a lot of shoot out accounts. My knowledge of him.
I really never paid much attention to his or others articles or vids on tactical advice. There are basics, sure. But if I believe that if a guy survives a shoot out or 5, he can only relate to those, as all can be a new set of problems. Few if any are worth our time.
