For me, this is the key. Are you creating your own style and forms?
If you are creating your own style and forms (or not) then I would not call what you come up with TKD. Let me give you two examples:
1. Some 3rd degree TKD black belt moves to town and he wants to get his 4th degree in TKD. He find STKD (Skribs TKD) and shows up. He has the expectation of seeing some type of TKD forms that he is used to. Instead, he sees totally different forms he has never seen before and or he sees a totally different modality of teaching. He won't be too happy about it and he may go write some interesting reviews about someone claiming to teach TKD, but is really teaching something totally different.
2. Some newbie to martial arts, wants to learn TKD.... he saw the Olympics, or he heard about it. He signs up and trains for a few years and then learns that a traditional TKD school works in an entirely different way. Even worse, he goes on vacation and takes his uniform and visits some other TKD school as a TKD brown belt, only to learn that what he learned is totally different and not traditional TKD.
