Took a look at the link to the article, and I don't really find it all that interesting.
Beyond the fact that it's a rehash of the same old stuff (train realistically, your fine motor skills won't work under stress, etc. etc.), beyond the fact that I think anybody with half-way decent training knows or can figure this stuff out for themselves, there's the fact that I (but who cares?) find this sort of thing deeply, fundamentally wrongheaded.
For one thing, it's a good example of marketing the same old stuff (not that that's bad!) with a different label on it...in the end, what this guy's teaching is the same stuff that anybody competent has been teaching for ever and ever. Why should we be impressed? I'll bet, in the end, that he gets about the same results as most others...
Look, it's easy to put out truisms and generalizations about martial arts training. It's easy, too, to suggest, "train my way, and you'll become invincible." But it's the day-to-day stuff, worked on over years, that matters...
As for the stuff about Raking Mace, well, I too thought it was, "grab and yank in, Raking Mace," and "grab and push back, Twin Kimono," but then I tend to kind of clumsily fall into techniques...wait, that's what's supposed to happen.
In this case, there's a problem with erasing a distinction between a pull and a push. I'd point out that there's much the same issue in, say, a rear attack that pulls one back into Twirling Wings, and a rear attack that pushes one forward into Circling Wing...
I think that those fundamental oppositions are essential to "mapping out," the territory of kenpo...
Oh yeah, forgot. Sure, you get grabbed for real and the latest and greatest tech will fly right out your ears. This is not an argument for learning only the simplest techniques. It is an argument for, a) learning techs slowly and in a rational order, so we don't get unrealistic ideas about what the latest and greatest high tech will do for us; b) a lot of long slow, boring practice to engrave the techs at a fundamental level--to internalize them; c) slowly expanding one's knowledge NOT so that the latest and greatest can be used in, "real," confrontations but so that the simpler stuff pops out to be used; d) slowly expanding one's knowledge, including stuff like extensions, to expand the "simpler," techniques....My offhand guess is that pretty much, the stuff you'll use spontaneously is--or should be--at least two belt levels below your nominal rank.
Then there's the whole argument about learning options...
