Damn. I can't seem to articulate what I'm wondering about very well. I'm not referring to training methodologies, i.e. kata, shadowboxing, drills, but techniques that are taught as self defense that aren't from the "core" of a style or system. I got thinking about this when I visited a school a couple of weeks ago. The first part of the class was kata, the second self defense. It being primarily a striking art, I was surprised to see what was labeled as SD was more like Japanese jujitsu. Lots of standing grappling. Now, I know about bunkai, but I really don't think that was the case here.
Hopefully, that makes my question a little more clear.
Normally, I'm not this obtuse, am I? jeesh
