I've trained with Takeda Sensei on a couple occasions, including at the dojo in his home, and have no reasonable response to those videos.
I don't understand what it means. Is it that his training is radically different from what he shows in demos, or on the contrary that it is very similar and seems to provide no realistic explanation ? Or perhaps do you mean something else.
My question is genuine, I have no opinion on the subject so far.
