So - I think - it may in the long run pay off to be rather bara bara.., but it will be frustrating on the way.
That is kind of what I was suggesting at the start. However, I am also reminded of the phrase “man of many talents, master of none”. I liked your link on Decision Training which is an interesting study, but it seems to me this is still part of an organised training programme (controlled exposure to “bara bara” learning). And it could be argued that some elements already exist regarding this within aikido where as I see it, kata are meant to be living, adaptable matrices rather than dry fixed forms (hence initially different but ultimately analogous multiple forms of training such as the ken, jo and unarmed techniques, the kotai forms verses ki-no-nagare, etc).
