They are but two principles. There are many. Let's say I were to use one other than those two as an example. The principle of the circle. Straight away you could view two clips from that one view and examine which person was employing that principle more. Thus nothing to do with who was better or more effective but aids in the recognition of comparing and contrasting what exactly is being done.
Thank you for explaining with reference to the other principles you were alluding to. Taking the example of the circle, how then do Tissier & Moriteru Ueshiba apply this principle differently?
