Hi:
It is, or it should be no secret that Yakusoko OKK wise has three interesting points:
1. It respects Kyu Kumite to the point that at least one point was lifted intact into the new advanced Kumite.
2. It follows the theory that every point must "finish", ie: the Defender gets the last shot.
3. It does not encourage the 'circling" motion (with the exception of point five of OKK"S) that creeps into "Dan" (also a Yakusoku) Kumite.
As a bit of old/new news the "arm pounding" of Kontikitai is not used at all as a blocking drill, but just as a conditioning drill. Some Sensei's views on Arm pounding I find a bit 'sanguine".
In the first hit of the sequence, the candidates had a marked tendency to hit the Liver 8 pressure point, or very close thereto,
I adhere to the theory that this should be a conditioning excecise, but 'whaling away" on or near to a pressure point is not conducive to anyone's "condition" . When I question the student's Sensei on this matter, the response was "they should know better". so each of us must make a choice, let the student injure themselves, and they will learn what they learn from it, or explain that the extra time taken before the strike in
Kontikitai is intended to allow the student to get into the habit of not hitting the same place too often and not try and condition some Kyusho points at all.
Some points can be protected by buling callus, calcium deposits (a difficult trick) or muscle over the point.
But such points or few and many that can be so protected from a strike are still vurnerable to grasping and twisting attacks.
