As for something lost in translation? It's funny in a not so funny manner that I trained with some one who was there when Ueshiba was teaching and quite a few of the exercises that Dan learned down through a Daito Ryu heritage were nearly exact to what Ueshiba taught. IP/aiki has specific training. It was passed along, it didn't get mistranslated, but all of it wasn't taught to everyone.
Funny how ages-old disciplines and skills, such as musical-instrument playing, blacksmithing and swordsmithing, etc. can be handed down generation after generation with their integrity and specific "recipes" intact, yet when it comes to IP/Aiki people are willing to put blinders on their common sense and deny that these skills, too, have been handed down intact along the generations. In any discipline there may be creative tweaks to individual artistic expression, but the essential integrity remains because the basic methods and principles have not been messed with.
