Mr. Williams used to tell beginner students that it took about 1 year for every belt level or rank. When our first belt was still an orange belt, promotion was possible in 4-6 months. Then of course progression through the higher ranks, colored through advanced levels, had an extended period of class as well as practice on your own time. 5-6 yrs is probably a good time for the shodan level. Having experience in some other arts, and from what I have seen elsewhere, alot of systems do seem to have less of a timeline. Alot of mimiced techniques up to the first Dan lavel, and then they try and tweak the movements. It is as though they wanted to rush the students. To the semi-annual, black belt tests. It is a far cry from the discipline for every technique, that I learned reguardless of rank.progressing through Eugue Ryu. We had additional study sheets of terminology and required techniques per belt level, besides the yellow book. I believe in more indepth study guide or instructors manual may be necessary to keep all Eugue Ryu standradized where ever it may be. Kata for instance is one questionable area. Additional katas were added, dropped, or not taught. For instance, Ni-Kyu is not listedin the old yellow book manual. Neither is sanchin, kusanku, or Nianchi 2 & 3. Yet Yanku is. And I don't believe anyone, has any recolection of it any longer. I believe Mr. James thinks tha Ni-kyu is not the original version that he had learned. I believe from our conversations, that there maybe only segments of Ni & Yan that he recalled. The kata that we perfome in KC is strongly reminience of Tang so Doo. Excepting of course, seiuchin. Which seems to me more closely along the lines of an Isshinryu version I came across. I think, but of course I could be wrong, Nianchi 2 & 3, and kusankyu was added to the ohio schools curriclum in the 80's. One question for those who do know. What is the closest adaptations that these 3 additional forms were adopted from?
