Re: Outer Seams and Ikkyo Curve (OK) but Inner Seams???
I experience that a center of gravity can be moved. in fact it can come right out of the body. Look at high jumpers who use the Fossbery Flop. Arching their back over a pole, their center of gravity is actually below the pole.
Perhaps my physics is at 6th grade level, but it has provided me with an ability to reverse-engineer a portion of the Ropokai (Okamoto) techniques.
But I do thank you for sharing your use of "One Point" and how it relates to your model.
Thanks for your input. : )
