Uh, it does where I live. Having a philosophy degree does as well. Naturally, no discipline covers every form of experiment, but frankly, if you don't use the scientific method, you aren't using science. Similarlly, if you don't get a degree at an accredited college, it isn't a real degree by any reasonable standard.I have an Masters of Science in Computer Science. Does that mean I have very formal training in every aspect of the scientific method?
Perhaps it comes as a shock to people that cherished buzzwords do, in fact, have actual meanings and standards.
What SL-4 advocates promote is that there is an interpretation to kenpo that was never written down that works in a certain way. It's "scientific," but which has no associated double-blind experiments or even videos of the concepts in action. It decries traditional approaches while describing elements in patently pseudoscientific terms ("circuits" that have no anatomical existence, for instance).
Here's an analogy.
The Ford motor company gets broken up into smaller companies. One of these companies claims that Ford secretly tested a 500 mpg car. If you qualify, you might be allowed to buy it. The car looks exactly like a 10 year old Escort, and every part looks like an Escort, but they claim it's been redesigned at fundamental levels (you can't see). Also, there is no proof the car goes 500 mpg aside from testimonials from folks still making their payments, and you are not allowed to look at the car in action or see the specs ahead of time.
I wouldn't buy the Ford SL-4 in a million years, plzkthx. It might work, but I already have a car that works.
About slapping, though:
In CMA, slapping usually helps to develop a little bit of explosiveness while setting up for a trap. The key is to realize that the distancing involved would, IRL, rarely allow the slap to continue. But the time palm meets bicep (for example), the forearm the bicep is attached to is already going through the opponent. The slapping hand also develops tactile response so it is a living guide instead of a static block. A hand should never be just positioned, but considered an actor in the technique. The sudden resistance trains you to momentarily apply force to that hand, but only in response to what you feel.
