A lot of the kihon I have experienced in aikido (and I have trained in dojos of four respectable traditions for some amount of time) is structured in a way that it will actually, at some point, have to be unlearned again in parts if you want to become what I consider really good.
Isn't this part of the "classical way" to teach and learn certain arts like aikido using the method of kata?
Isn't this described in parts by the development modell of shu ha ri?
Isn't this due to teaching things first in the omote version and later (often very much later) in the ura version? (I don't mean the use of "omote/ura" like in ikkyo omote and ikkyo ura.)
I practice for over 18 years under the same teacher/s now. I had to unlearn and relearn the (very same!) kihon two times now.
