i have not had the pleasure of attending one of these training classes, i'm largely self taught. i have been shooting IDPA for the last 2+ years, and that's forced me to learn some new skills too.
but from reading various course descriptions, they all seem to plan to talk to you for extended time periods and then to have you try various drills on the range. very few promise that you will improve your skill that day, which makes sense, as you only get better with more practice on your own (like doing math homework).
so i like hitting the range as much as anyone, but i'm not sold on spending hundreds of dollars to either be taught something i already know (how to draw, shoot on the move, shoot from cover...) or to be taught something that i can't possibly do (like draw and fire 6 shots on target in under 3 seconds, i'm too old for that trick).
and i certainly would hope that I would immediately pack my bag and leave if i saw something like that at a class. y'all have fun, i'm going home so i won't get shot here.
