Again, you misunderstand. You have a claim of TSD schools in the 1950's having similar technique to TKD. My point being outside of the Oh Do Kwan which was the singular military gym at that time there were few if any TKD schools so your point has no merit. Of course the Oh Do Kwan which contained many CDK alums trained in TSD would have had people who retained some TSD habits.
So, once again I ask if you have any support for your point and if so please specify any TKD schools outside the Oh Do Kwan that even existed during the time frame you specify? So far all you have is some video of Koreans Kicking and punching that someone labelled TKD.
