Hi,Don.
I think I am so lucky to obtain such clear explanation and guidance from you. I am so happy.:))

Before, I used to focus on rising my poor right ankle , right hip and extending my right side, avoiding to press my coach right arm and being alert if my waist and hip and my thigh and ball+toe are in same surface.
Now, I added the following points in my mind:
1. Sway is an inclination away from a fixed point . 2. First swing then sway with straight legs carying body moving toward the new standing foot , stretching both sides equally. do not neglect the inside.
I believed that these new factors will benefit me to perform a better swing .
I took off my shoes and swing on the floor of my clinic...

Yichen 1. I am glad I was able to help. Another important thing which is never spoken about is the position of the lady in relation to the man. Some teachers say that the ladies right bust should be level with the mans shirt buttons which is giving one position for all shapes and sizes. Nothing can be further from the truth. The lady will be more to her left if the man has a longish arm. She must fill that space. One of our top dancers now one of the most sought after teachers, if you danced with him the ladies right toe would be level with his right foot.
Much more to her right than with a man who doesn't have the same wing span. The connection has altered a lot since I first learned. It is now right side to right side. And the conection is much higher. At the pelvis level there is a space which you could swing a brick through without touching either person. This gives much more freedom than in the olden days.
