Mr. Parker said it many times. In other words, the Ed Parker Kenpo System is not being taught, however, individual interpretations are. Your effective interpretation is all that mattered. He then would give his blessing or suggest changes to make it more effective, but he never told you how any technique should be done. You cannot have a system without execution specifics.
All techniques have at least three components.
A method of execution, a manner of execution, and a self-defense theme. He left the method and manner up to you. After all, it's about self-defense. Huk Planas would concur, because of his first hand knowledge in the creation of much of that material. Not that these motions couldn't be used, obviously they can, and quite effectively.
