It does make sense and I share your thoughts.
But, not to be all M4-carbiney about it, I didn't know what I didn't know. I thought that was what I was *supposed to* do. And while I mostly blame myself for being duped, the whole branding of fear in the training industry doesn't really do the students any service, in my retrospective opinion anyway. And I bought it, hook and all, probably because I wanted to.
But I had a boatload of fun, enjoyed almost every minute of it, and stopped doing it when it stopped being fun. In terms of the experience I have no real regrets, and met some of the best people ever along the way. But that's different than becoming a better shooter because of it.
What I am saying is not that I needed to take the classes *and* do the outside practice, I'm saying that the outside practice alone would have made me a better shooter hour-for-hour, dollar-for-dollar, round-for-round, once past the first couple of classes. In fact, I'd say that some of those subsequent training classes probably did me a disservice and resulted in less-gooder shooting not moar-gooder.
