It would depend on the instructor and and his situation at that particular time and exactly where he is in his art.searcher said:What I am referring to is the formation of a new system. If you really want to get down to all styles are "sub-systems" of another style. For example, Shito-ryu as created by Kenwa Mabuni could be listed as a sub-style of Shorei-ryu and/or Shorin-ryu. General Choi's TKD could be classified a a sub-style of Shotokan, just the same as Wado-ryu and many other styles. My current style could be called both Shorei-ryu and Shorin-ryu just like Shito-ryu, but they are different. I hope this gives you an idea of what I am talking about. Where does the diferentiation occur. When does it stop being one and change into another.
Thanks to everyone for letting me pick your brains apart. I love these touchy subjects.
Actually you're partially wrong. A sub-system still exists on the family tree. Your example would not include that. It m,ay exist in the lineage being traced back but not on the "family tree."
I would venture to say that the sub-systems you mentioned are new systems and not sub-systems but you know your system and I don't.
