Well there are alot of differances. First off knowledge of the various ryu-ha is the biggest deal. Proper kata's and henka off of them. Bussey studied only for a short while before adding things that we not Bujinkan related. Besides knowledge of the ryu and there kata's the other distinguishing features of Mr. Bussey's style is high kicks, acrobatic moves and flash. Mind you many people in the Bujinkan are not Bussey fan's. However he was around pretty early on and blended his hapkido training with Budo Taijutsu and then marketed it during the Ninja boom. Personally if he inspired anyone to find legitimate training under Hatsumi then more power to him.
Thanks, this was helpful!:ultracool
While I'm not sure the exact timeframe it takes to be remotely good at the things you mention, I'm sure its not going to happen in a short time. I get the impression from reading Obliquitys' post, that Bussey didn't seem to think that what he was learning would not be effective ASAP. Considering, as I said in the beginning, that many things could take years to perfect, would this be one reason he added/deleted things? Is there anything "Bujinkan like" in anything that he is doing now?
