You are going to get criticism. Yet, you must keep going in your direction.
Ok...to explain it. I often use a bottle filled with water to explain how the technique works. The outside to the bottle or the skin does not move. But, the water inside the bottle changes its "center of gravity" as it is poured to the top or bottom of the tube (bottle).
As such, the placement of the "lever and fulcrum" does not change in the throw. But, the technique is different because the center of gravity changes.
Once you have this control...the throw seems effortless. In watching O Sensei "the standard" for us is being able to repeat his "effortless throws".
