Do you have the Japanese text of Budo? There is quite a lot missing from the explanation on p. 154 of the Saito volume.
Yes, I know - I mentioned it because of the problems with the text they cite and the explanation provided - even with the English translation of Saito's Japanese explanation.
I have some of the pages from "Budo", but I lost quite a few in one of my moves across the Pacific.
