The subject of what I'VE been writing and curious about is exemplified by the following quote of Okamoto Seigo.
Kodo Horikawa Sensei used to say: "Once you reach a level such as yours, you become able to execute your own techniques based on what I have taught you. I didn't learn all the techniques I do now from Sokaku Takeda Sensei." Once you master a certain level and grasp the key points you become able to execute techniques of your own. Then these techniques of yours gradually sprout branches."
AND at a certain point, when one deviates enough from the source, one is required to rename it. (Ueshiba - aikido, Inoue - Shinei Taido, Mochizuchi - Yoseikan budo). Christ - Tomiki got in trouble with the aikido folks because he DIDN'T RENAME IT, given it was seen as "different enough"
