Ken. It's very simple really. They are trying to prove that the internal stuff or aiki that Takeda had is the same that O'Sensei had and used as Aikido.
Completely false in my opinion, but they are trying to prove it. That's the nub of the matter as I see it.
Such bits of data as O'Sensei was largely retired after the war or even that in his later years didn't really have much to do with teaching Aikido to me are completely false.
It's best to let them get on with it for obviously it is their path.
really?? take a look at the video Lee posted of O Sensei and tell me this process doesn't require internal strength and perfect body allignment. In fact, I'm pretty sure, as far as I know, that nobody has replicated the Jo horizontal position, albeit as a trick using the centre as resistance, which he obviously isn't doing in this with his arms extended.
Anybody able to answer my original question, we seem to have swung wide of the subject??
