This is part of the problem. The only "objective" evidence in your eyes is for something to be proven with the field of consensual/sport/fighting. But Karate kata isn't designed to function within the realms of consensual fighting, it is designed for self defence from non consensual criminal violence.The best evidence would be objective evidence. However, since exponents of such styles refuse to compete in open formats, that objective evidence will never appear.
“The techniques of the kata were never developed to be used against a professional fighter in an arena or on a battlefield. They were, however, most effective against someone who had no idea of the strategy being used to counter their aggressive behaviour.”
Consensual fighting and non consensual criminal violence are two different things. So you cannot measure the effectiveness of one by testing it within the realm of the another field that it was not designed to function in, anymore than you can test the effectiveness of a screwdriver by trying to mow the lawn with it.
You don't understand the problem (why consensual fighting is different to self defence) you don't understand how to interpret the movements within karate kata and you don't understand how to apply the techniques of karate kata for SD. There is no part of this discussion you understand. Further, the only evidence you will accept is for this to be proven in a field in which a) it is not designed to function and b) has been decided by you as the only true test, despite not understanding any part of the subject.
It is perfectly understandable then that you don't, and never will 'get it'. And this is not a problem. You don't understand any part of the problem or the solution, and this also isn't a problem , as has been explain your inability to undestand something does not diminish it effectiveness.
But this does not mean that you should be arguing with the people that do understand the problem and do understand one solution, that their solution will not work because it is not designed to function within a completely arbitrary measure that someone, who does not understand any part of this, had decided is the only true way to prove effectiveness.
You know about BJJ, I know little, hence I don't try to tell you what does and does not work within BJJ. You know what works, you done it, and the inability of other people to understand how it works has no bearing on its effectiveness. What I don't get is why you continue to argue with those of us who do understand the difference between consensual fighting and SD, and do know how to interpret and apply the the techniques of karate kata, and have done so in live situations, that our solution to the problem does not work. It work, we know it works, we do not need to prove to you it works, nor do we require you to understand how it works, nor do we need to prove its effectiveness in a completely different field that it is not designed to function in. What we do require is that you stop arguing about a subject that understand absolutely no part of, with the people who do.
I took my son to the hospital easter weekend as his was in severe abdominal pain. The Doctor told me they were going to rush him to theatre to perform an apomdectomy. I did not ask the surgeon to prove his diagnosis by beating me at monopoly because I had arbitrarily decided that is the only true test of his ability to understand both the problem and the solution. I know nothing of medicine, he does so I listen to him because he knows what he is talking about and I don't. Now my son is recovering well and we are sat here waiting for Dr Who to start, instead of organising his funeral which is what we would have been doing if I tried to have an arguement with the Dr and tell him he was wrong because he couldn't beat me at monopoly. This is, as idiotic as it sounds, is exactly what you are doing.
You do not understand what SD is, you do not understand how to interpret the movements of karate kata, you do not understand how to apply them to SD, and you do not understand the difference between consensual fighting and SD, so you should probably stop arguing with those of us who do, accept that you don't understand (and never will) move on, and stick to talking about the subject matter you do understand?
