Where do you get your figures? How did you come to this conclusion about 95% of practicioners not picking up the martial art?
Is this an opinion, or a hard fact?
I can only give you opinion, not hard facts.
My opinion, based on personal observation, is that 100% of those who seek out a teacher of genuine, martial TCC, and who want to learn the martial art, will learn it.
100% and not one person less.
The caveat here being "who want to learn it". Because you have to want to learn it, and practice like you want to learn it, or you won't.
I frequently and loudly recommend the Kempo Karate school down the street, where they have a basic self defense course that you take in two weeks and their own brand of something or other the Master there invented on his own and calls TCC, to those who ask me about TCC classes... IF all they are looking for is an effective self defense technique that they don't have to study very long or very hard to learn, and something that they can call TCC to be nouveau cool.
Why would I do this?
Because they're NOT looking for TCC, real, genuine, martial, healthy TCC, they are looking for a quick fix.
I have only met a very small handfull of people who are even the slightest bit interested in the "real" TCC, the martial, hard to learn, can't fake it, can't gather it by osmosis, art of TCC. Just about every single student I've ever run into, and that includes those at current and former schools, are looking to be able to SAY they are practicing TCC, but don't want to put in the time or effort to learn it.
There is no quick fix. No short cut. No getting out of the grueling hours of practice required to reach the level of actually knowing the martial art of TCC and how to use it.
How many of those who post on this board can honestly say they've defended themselves using TCC and it's techniques? I'd wager not many.
How many would be able to say, honestly, that they even know how to defend themselves using TCC and it's techniques?
I am happy to say that I took the time, put in the effort, did the research, practiced many, many times when I didn't feel like it, didn't want to, wished I was doing anything else in the world, and learned enough of this crazy art to be able to succusfully defend myself using the principals I've learned from this art alone.
Not every time, not in every circumstance, because I do have a hard style background and I have used some of those techniques and principals when defending myself or others, the notable time being when I had to defend my wife as mentioned above.
So I still have some rough edges to work out. I most certainly would not, at this time, attempt to defend myself using Yang style techniques, not even after nearly three years of studying them. I feel certain I would rely on the Wu style techniques I learned previously.
I'm much more familiar with them.
For example, just this past Saturday morning I found a major defect in my Yang style stances, it had to do with the placement of my back toes in relation to my back knee, and it totally undermined my root in those forms.
I'm working on correcting it, and have for the most part, but until these little bugs get worked out of my Yang style forms, I certainly would get myself in a world of trouble if I tried to use them in a real world altercation.
So after three years, I would still resort to the Wu style in which I spent nearly fifteen years training.
That's how hard this stuff is to learn, correctly.
One little defect and I might as well have been doing Yoga.
Fortunately, I have a skilled instructor, who also took the time and effort required to learn his art, and he noticed the defect and corrected it for me.
Sure answered a lot of questions I'd been having about why I always felt kind of mushy in Yang style bow stance!
My point is that 95% of people who take TCC classes may not "get it", but those 5% are the ones who come to actually "do it". That's your real statistic.
