I think the complaint with this is that you have essentially made up your own method and nobody is quite sure what it is. I don't think this has anything to do with "can you use it" and more to do with "can you teach it". You're not a teacher, so, probably not?
" I don't label myself as a teacher"
Meaning this is not the way I look at myself..
Others do "label me as their teacher"
My label as my teacher's label was.
Is "practitioner"
The method followed is very well documented with most of the other practitioners, who follow it able to do the same things at a deeper level...
but it's equally important to point out that at a certain point you don't really have the kind of credibility to just walk into a dojo and tell jujuitsu people how to train either.
Why would anyone do that?
I don't practice Jujutsu, although I have interacted with some practitioners from time to time.
My credibility is based on those who have experienced my work in the US, China, and Taiwan, and among my peers.
What more does one need?
Unfortunately, "can you use it" is not the be all and end all that it is supposed to be for most people. This is an important reality which we have to face especially in the modern world where most people will never have a serious fight in their entire lives.
Being able to do what one writes about is a pretty basic requirement.
Would not presume to know what others face in their lives.
Don't know what challenges people encounter,
Only know what those I work with look for.
