Video? I train regulary in the Yoseikan lineage for some 8 years now and being flirting with Iwama Ryu for some years too. Aikikai 10 years now. I know what I'm saying. Video? Who said video?
You didn't answer the question. How much direct physical knowledge do you have of the differences between pre-war and post-war aikido, particularly as practiced by uchi deshi from those periods?
Just because a dojo belongs to the ASU, that doesn't mean the chief instructor -- much less the students -- has any ability to replicate what Saotome Sensei is doing. So I'm generally skeptical of the assumption that a particular lineage necessarily replicates the aikido of its founding instructor.
