The forms don't teach direct applications.
----In WSLVT!!!! But we aren't talking about WSLVT here, now are we???
We were actually.
Because you said;
"you always make your system [that would be WSLVT] sound so abstract that it's hard to conceive how it actually works...".
To which I'm replying that it's not hard to conceive at all. It's just that the forms don't teach direct applications, while that might be what you're mistakenly looking for to understand it.
---Like every version of Wing Chun other than WSLVT (at least according to you) it is both concept-based and technique-based. Specific techniques are what make the system distinctly Wing Chun. And those techniques are guided by the concepts behind them as well as the concepts of the strategies and tactics of the system.
You aren't answering the question of how this differs from any other MA.
Sounds pretty meaningless to claim a conceptual base to set your style apart, when what you describe is no different from any other MA.
