What is the hip center? Is it the seam on the pants? How does it
relate to the center of body mass talked about in the "final missing
piece"? Does the edge of the hip go past the ball to get the
center of mass next to the left leg? Or does the the 45 degree
backward hip turn get the hips even with the ball? Would be nice
for V.J. to comment on these questions.
