But you're missing the issue. You're comparing long-term training in BJJ to the quick results from DT. They are not comparable. Both together is better than either alone.Nope. That is why you don't get 2 week BJJ programs.
Ok. Provided the instructor has a real mechanical grasp on the technique. (And that isn't guaranteed. And if he doesn't guys who do understand the mechanics are not able to imput)
They compromise on time.
And therefore compromise on techniques that take time to learn. So because they have easy to apply but potentially no longer high percentage techniques to work from they have to manufacture wins within the training.
So things like sparring go out the window. And they start using combat scenarios.
All of this make any approximation of how a real fight works goes pretty much out the window.
But they also set the standard of what is expected in a real fight. So restraint and control is expected to look like the training. But it doesn't because they are not training realistically.
So this is supposed to work in a fight.
If it doesn't work. Then you are doing it wrong.
2 weeks is current reality most places. It just is. Wishing it weren't doesn't do anybody any good. DT accomplishes quite a lot in that time.
As for the rest, that's still more suppositions. Yes, there will be some scenario training with established limits. That's an efficient way to make sure you cover what's more common, without getting dragged off into wild scenarios by folks who want to find out every "what if". I know for a fact that some DT involves actual sparring. How common is that? Dunno. I'm sure it's not very extensive even in those programs that have it, because there's such limited time to work with. But it does happen.
So, is long-term training in BJJ (on top of DT) better than just short-time DT? Hell yes. But that's not BJJ being superior. Long-term DT - where it's backed by actual experience and uses good information and feedback - would also be much better than short-time DT.
