In demos I could agree,but in the context of ph training sending people flying is merely using (usually) long power to enable one to practice issuing on another person without damaging them,a very standard practice-'cause if you have to wait ten minutes for somebody to recover from a sucker punch to the liver not much training is gonna be happening.Long power uproots in and of themselves are neither watered down nor sporting aspects. Of course it's certainly not the only kind of issuing that should be practiced in ph over time,it's a basic skill. Now,if that's all an individual can do then they have a very limited skill in issuing,so you could say if that's all they can teach in that area then they are indeed teaching a watered down version-if they're saying that's all there is rather than admitting to their limited skill/knowledge. As you know I somewhat detest the term "internal" but for the sake of definition in discussion I use the term but only as regards that which can be observed/measured-which is to say the mechanics found in some systems which are cultivated by those gungs. An initially conscious control and exercising/segmenting of muscle groups neither normally utilized in certain ways and/or not under conscious control prior to such training. I've yet to speak with any "pure" Karateka who had a clue about things like expanding/contracting connective tissues or opening/closing joints in the manner developed by those gungs. Based on years of observing,listening,discussing and reading my own conclusion (perhaps erroneous) is that Karate doesn't have that kind of "internal" power.Not to say that it's an impossibility that someone may have such teachings locked in their "cabinet of secrets" only for their successor or something.
