Your comments just strengthen belief that the koryu system of not having ranks, but only teaching licenses for various levels of the curriculum, is the right way. The whole dan rank thing was a huge mistake on Kano Shihan's part. All the questions and debate I see here vanish with a licensing system.
It seems to me that there is enough politicking and infighting over licenses to negate that point. Apples and oranges they may be but they are both fruit. If anything there are more dan ranks per school so maybe its a matter of degree. <-- pun alert.
