Likewise there are two levels of understanding. One which is kept by the elite of Japan's karate community and the other which is preached to the masses. These points are taught behind closed doors and will never be taught outside the elite。Overall, the karate microcosm perfectly reflects elitism in society now, and historically... and logically so. Why wouldn't it?
The breakthrough is for an outsider to become an uchideshi of someone 'in the know'. A personal student of someone of high seniority in Japan and of high technical skill. This results in something very special.
Returning to the movements of karate, besides the timing differences between sports and martial art karate, there is also extreme movement differences. The sport karate movements have many superfluous actions; whereas, bujutsu karate eliminates as many as possible.
