You are lumping Mary, and me indirectly, into a group to which we do not belong. Please understand, we are not opposed to "the IP thing". Personally I think it's great that folks are finally beginning to see the value of extending their training beyond the waza only model. We have been exposed to internal training as a regular part of our Aikido practice since we began (over 25 years for Mary, ~40 for me).
Our training paradigm is different from the methods currently being espoused on AikiWeb. Different exercises, different goals, many of the same results.
I haven't seen Maruyama for almost thirty years - but what he was doing back then was really not much like what we're doing except for some very basic crossover.
I have no idea what you folks are doing, we've never met.
On the other hand, if you've never met Dan then you really don't know what he's doing either.
This stuff is different enough that most people who think that they're doing the same thing...aren't.
