I would think the approach chess takes of record what someone did and then subject it to post-event analysis (so the student also knows what was an inferior choice and why) is probably worth emulating in the more physical martial arts. But chess doesn’t have to deal with body types, age, nutrition, chromakey backgrounds, lighting  …

Still, these days if a Grandmaster or master can record a canonical version of a set, and show why he or she thinks it is best (applications, appearance …) and how variations are inferior that would be a gold standard to my way of looking at things.

Of course, then the real trick is to teach so that students do the set the way the master does. Not so easy.
