How many techiques/concepts do you feel a person can become proficienct enough in to actually perform in a real life self defense situation as needed.
Jason Brinn
To be honest I think it is the will to fight and defend yourself that matters more so than techniques.
I'm sure we all have read stories about the 80 year old marine (notice I didn't say former marine ) who defeated the would be robber, or the 10 year old kid who fought off the attempted kidnapper, the woman who beat back the rapist, etc. etc. Sometimes the people have training sometimes they don't and they still win (survive). This is why I thought your first question was valid, and this seems a bit watered down.
People without training can defend themselves and not have mastered anything in the process to executing the defense. Perhaps they had the stronger will to fight that day, perhaps the assailant had been to long without a mark and was weak from lack of food or their drug of choice, who knows. Perhaps it was wrong time and wrong place and help was nearby to ward off the attacker.
There was a blind man who taught self defense (I think on the east coast) who I would say mastered the chin jab (as taught in the old military combatives programs) (I think he lost his sight in service to our country). I believe if you grabbed the guy then he could turn the tables on you. The simple act of executing the chin jab for him was infinitely more complex than for those of us with site. He had to learn a different set of skills to make up for his lack of sight and yet he still could execute that technique well enough to defend himself. So much so that he developed a self defense course and he became a authority on the subject. How can we begin to quantify the skills, concepts, techniques, that he had to learn to create his own self defense program coming from a person who is blind. And yet if a person was out of reach holding a gun, or a knife, he was at a serious disadvantage and his training program didn't work. I MEAN NO DISRESPECT TO THE BLIND INSTRUCTOR NOR HIS STUDENTS, I'M TRYING TO MAKE A POINT ONLY.
So I believe you can master techniques that can be executed in real life and yet at the same time on the training hall floor.
