I wanted to observe the placement of the Power Hand during a sucessful, i.e. scoring, attack. The hand that transfers the Power of the throwing action and drives the opponent's back toward the mat. I also needed to decide, for purposes of easy reference, how to define the areas, on the defender's body, where the Power Hand was being placed. A Middle Range Power Hand was considered anything around the chest girdle and generally not below the sternum, in the front or lower than the scapula in the back. Description of Power Hand placement location areas were kept generalized in order to avoid a quagmire of minutia.
Any successful attack is an unique event.
It would serve no purpose to specify that World Champion X placed his Power Hand two inches below the clavicle, for Uchimata, while Olympic Champion Y used a Power Hand Placement one inch above the clavicle, for the same throw. A high grip is a high grip. If the opponent was thrown the Power Hand placement may be assumed to have been effective. I was not looking for Power Hand placement in specific technical applications, i.e. Uchimata or Taiotoshi. I wanted to see where the Power Hand was most effective when throwing to the general areas, i.e. Front and Rear Corners.
