Even if there are certain resonant frequencies that are achievable with a punch, aren't the tolerances going to be very fine? How would you know you have the right frequency, even if you are striking using a method that theoretically can produce it? It just seems to me that the idea of finding a certain resonant frequency that will extract a specific physiological effect has the same problems that kyusho will in a practical context. I.E, that while you might be able to demonstrate something under controlled, dojo, circumstances, you're really going to have a very difficult time getting that level of precision against a resisting opponent. And it seems like time-on-target vs. snap is a bit rough a description of something that has very fine precision. Maybe I'm wrong about the precision required, since I don't really understand the details of the kinetics and chemistry involved.
