This is not what I said, with clearing space I was referring to why you do the bong-sau.
That is a simple concept, not a "this vs that" application.
Hate to say it but all techniques are non-specific.
A lifting bong-sau was mentioned earlier as a remedial upward block. That is specific.
Each type of bong-sau that was mentioned has a specific function, and one would be used where another one would not. That is specific.
Why you do bong-sau I do hope is dictated by what specifically your opponent is doing. Sounds dangerous otherwise.
What's dangerous is chasing hands. Why I do bong-sau is dictated by position, not a specific technique to use it against.
It could be a number of things. Surely you haven't forgotten what I've been repeating to you countless times already in this thread??
Needed function can change your technique, without being application based.
That's the very definition you just gave of "application based".
If the concepts dictate something you may identify the need for a specific outcome/result. As such you change how a move is done to affect the result to your benefits.
What concept? If bong-sau can be to "hack, cover, support, bar, lift, sweep, bump & pull", then it has no clear concept.
Imagine this, you know this person is weak due to an injury in one arm. Instead of following what you would normally do you instead take advantage of the injury to your benefit.
So instead of punching them in the face, I chase their arm?
Application based is if you have a specific technique done towards you dictating that you change your bong-sau from this to that. Rather than it being the way to adhere to your concepts.
That's exactly what "hack, cover, support, bar, lift, sweep, bump & pull" is all about. You wouldn't cover what you would lift. That means you are changing the bong-sau to perform a different function against this or that.
Just because a technique can to two things and there can be a decision on what to do, does not mean it is application based. You could just as well break them down to two separate techniques, one for hacking, one for pulling. They are in fact different movements.
You wouldn't hack what you would pull. They are dictated by whatever they are being applied against. It's application based by your own definition.
