From reading Shioda, he calls what I said was Aiki, Kokyu-ryoku. And what the IP/IS crowd is calling Aiki, Shioda calls Shuchu-ryoku.
Ah, no. IMO, Chushin Ryoku, Shuchu Ryoku, and Kokyu Ryoku are sub components of aiki. They are specific physical parts that can be trained internally. You'd need all three and more (opposing sides, spirals, etc) to have aiki.
