i believed i talked about this in one of the thread. when you have not the body that worked with this stuffs, you will be blind and deaf going in. you can feel your balance broke by Ikeda sensei, but you wouldn't be able feel what he did to you or be able to reverse engineering it. Ikeda sensei said, which i am paraphrased, "dan ranked no guaranteed you understand this!"
i believed i wrote a bunch of stuffs on translating what Ikeda sensei said somewhere.
Yeah I remember reading it - not sure if it was on here or QiJin though. Either way, yes, it's not so easy to pick up unless you've been with him a long time and working on it with him or obviously if you've met up with Mike or some of the others who can explain a few things.
He also mentioned that grade doesn't matter and that sometimes it's worse with more experience because you have to learn a new method of moving.
