The problem is that this is absolutely nothing like martial arts training. At all. As a result, they have no real relevance to your martial arts perspective except in your personal philosophy, which isn't anything that we would have a way of relating to. Except that we have repeatedly pointed out that this method doesn't work for martial arts. There are just too many differences. The training needs to be relevant to the skill and application. This method is not when it comes to martial arts. Not a problem, but you may want to rethink your approach to those who have spent years, or in a number of cases, decades learning this stuff. Continually arguing against those who genuinely do know better because you want to assume that everyone has a limited experience will just get people frustrated in dealings with you. Honestly, it's really not relevant, and the only way for me to really take you through what it is, and why, would be in person (that's the way to learn these things), so there's no real need to answer. But, so you know, the reason you don't just go for the Boshi Ken is that it won't work. Sometimes statements will certainly stand on their own feet without it mattering who they come from, but when it's a discussion of methods of learning, and the person putting forth a pro-DVD argument seems to be displaying no idea whatsoever about martial arts and the way they work and are learnt, the context of who exactly is saying it comes into it. If you're just a person who has seen some Bruce Lee films and has made some uninformed decisions and beliefs, that's a fair enough reason to not listen, if you turn around and say "well, I've trained in 5 systems over the last 30 years, I hold X-Dan in this one, X-Dan in this one etc", then things are a bit different. This is why that particular question, whether it interested you or not, was actually quite vital to the discussion. Now, your profile lists TKD, and this is the first indication of any rank that I've seen from you. I would ask, though, how you knew the school to be a "McDojo", as that is coming across as a value judgement at the moment, and as you have not mentioned the art yourself, your answer is still far from "clear and concise". Let's see if we can get something solid. How long have you trained in TKD? Do you still train in it? How long ago was it, if you don't? We'll start there.
