A more accurate analogy, given my not-so-deep understanding of kata, but my fairly good understanding of classical music, is between scales and kata.
Any good classical musician practices scales ad nauseum, and when they read music that has a certain portion of a scale, it is easy enough to plug that part in. The scale is the backbone, but not the whole of the music. Chopsticks doesn't get anyone far except my niece.
What are we arguing about here anyways? I appreciate Mr. Arthur's posts in the ninpo forum when I look in, and have found some other very good posts surprisingly rising from the morass.
Seems to me that the original poster is a bit confused on what gives a system its efficacy: the structure of the system itself and how much that system validates its own structure. Is it me, or are koryu and kan apples and oranges with completely different structures, and tastes?
As far as why the federations in Japan have not recognized Mr. Hatsumi, seems like that was quite reasonably answered a few posts ago--he hasn't found it necessary for whatever reason, and so has not endeavored to do it. While some ryu may not be part of the federations, it seems always the decision of the soke to try to join, not some members at the bottom of the pole wondering if their system is as cool as somebody elses'.
