How is this not kata? Is it any different than the iaido practicing the cut? He explains the concepts, imagine he is talking about karate. First practice shot is at 4:30 mark if your impatient.
Ultimately, I don't have a dog in this hunt. So, I say train what you like, and have fun. I don't think doing kata (whether it's like the gun guy above or the more orthodox kata that we think of) is going to make a person worse at anything. And some folks really get a lot of spiritual fulfillment from it, which is terrific. There is also a very legitimate cultural element, which I totally understand.
But from an objective training perspective, does kata actually promote skill development? And if so, does it promote skill development more efficiently than more dynamic drills? Or is it just something different?
In basic training, I learned to march and to fold my t-shirts into six in squares. In the remaining 3+ years of my enlistment, I used those skills zero times. But we did them because, at least, at the time, it was part of it. We did those things because everyone did those things. And we were told that it taught us some relevant skills, like attention to detail. But it was also widely known that only an idiot would ever use those t-shirts after folding them the first time. The trick (that everyone including the instructors knew) is that you lived out of your laundry bag and never touched the inspection ready clothes. So, why did we do those (and many, many other things like them)? Did they actually teach us anything other than to march and fold our laundry? At best, it's an open question.
That's how I think about kata. Does it teach you anything other than to perform a choreographed set of movements slowly and deliberately? At best, it's an open question.
