So then the privates should stop after Orange Belt then if the goal is only to learn to defend oneself faster eh? Once that was accomplished, no more need for speed.
no, there is always more to learn, but that's a personal choice.
But if one was ONLY interested in self defense, to the expense of anything else, just a bare bones method that gives you good options for many scenarios, sure, you could stop learning any of the formal curriculum past Orange. I would personally suggest you go thru Purple, it'll give you that extra edge, but yes, you could stop learning more of the curriculum at that point, and just focus on what you know and get really good at it, and it would be enough.
Outside of kenpo, my kung fu sifu says that our first three hand-strikes in Tibetan White Crane, chien choi, pau choi, and khap choi, are enough if all you want to do is fight. If you get really good at those three types of punches, if you get fast with them and you can switch them up quickly, you could fight really well. But of course the complete system is far more than those three punches.
It's a myth to think that you need to learn a complete system and have high rank, if all you are interested in is the ability to defend yourself or fight successfully.
