I think this is where most of the confusion arises. In every dojo I have trained in (4 styles, 2 countries) there is no distinction between what is taught to people at different ranks. The higher ranks are just better at it, that's all.
Yeah, every dojo I've been at has been like that, too.
Personally, it never would have occurred to me to say anything about that because never having trained in any other martial art, I had no idea that was different in other arts!
