The only differences I see in 8-6 and 8-7 is that the left knee has separated slightly from it's Top position, and the shoulders have unwound slightly. We see a HIP SLIDE IN 8-8, because the left hip is closer to the edge of the picture, but the shoulders are still level here. Also... what is the "equivalent" of "the period of Shoulder Acceleration," mentioned in 8-7?
