If it's the latter, I'm not sure why it would matter. There are other names for most things, and which name we use for them doesn't much matter, so long as people are learning what they came to learn.Im gonna guess either that how you use ki is anecdotal, and not what people refer to generally as ki, or that you use ki as shorthand for these techniques, despite there being sport science that has verified ways the techniques/tricks work and names for it. Those are just guesses though, if im wrong than im just as lost as you
