What's interesting is this by statement by the author of the article:
"Morihei Ueshiba apparently did not approve of the kata training method, believing that "static" prearrangement of techniques interfered with the direct, spontaneous transmission of techniques from the gods."
In other words, leaving out the bit about "from the gods", Ueshiba did not believe in using kata. He also did not believe in using randorii, IIRC. The question becomes who is right in their recommendations, Ueshiba or Diane Skoss? Ueshiba or Tomiki? Lots of questions.
