Actually, yeah, some of it is. Did you miss my posts where I stated that some of the stuff I trained from Dan was exactly the same as what Ueshiba handed down ... outside Tokyo hombu. No, I won't say who or where. If you do the research, you find the trails.
I'm sorry Mark, I don't have any confidence in your ability to tell whether two things are actually the same, or whether you are overexcited by some fractional degree of similarity.
