It's all good. There's a difference in the energy levels of the uke in the two clips. But as far as the KM being increased effectiveness, I actually thought that would build more delusion, thinking you can crappy armbar someone and kick them in the face until they tap out. I mean there is such a thing as a good armbar combined with a good technical standup, which would be the effective approach to the KM scenarios. The limb destruction scenario is just very different. Like maybe getting past a boxer good high guard. You miss that technique and you get tagged and have to recover. You miss the KM technique and you get GNP'd into oblivion. I mean there's a lot of differences in those two clips, beyond the obvious.
I mean the best way to demo I suppose is start off low key low energy like the OP clip, then progress to handling a higher level of live energy, then show it sparring or free movement application. That is a supportable approach.
The one thing I do think the KM clip shows is you have to train against high energy simulating reality. If people train just like OP clip and never step it up to that level, then hand skill would never develop. The problem I think they run into that I see is they never slow it down to make their movements efficient all the way through and end up with kind of a flailing response under pressure. That would work against an unskilled or semi-skilled aggressor but not reliably against a skilled opponent. I see plenty of clips up in self defense scenarios where a bigger person can pass guard and damage. I really would hate to see a smaller female like in the clip go for a foom foom foom crappy armbar plus kicking because she's ranked in KM and just anger a bigger opponent and get hurt.
Ha. I'm funny today. Totally rail on a KM more live energy demo and give a pass to a guy videoing a lesson to a beginner level guy in a park. Beauty is in the eye of the beholder I guess. OP if you find someone that has chi sau'd a lot before throw up a video of a little more live action in the exchanges after the explanation. KM guys good energy but sloppy technique
