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.
I saw Maruyama Sensei at Nippon kan in Colorado in 2005. He was impressive a lot of up and down movement with little muscle. He was pounding the same uke for about an hour! I unfortunately never got to experience any hands on stuff with him.
Chris makes a good point having the other point of reference in the two different methods. I will be honest in never feeling anything like Dan or Sam ....ever. I know Chris has about three times more experience than me and living in Japan for an extended period of time. I think he a lot of IHTBF in his memory banks.
