I have noticed that the "measurement" show NO interaction or disruption of the angular velocity curves between adjacent elements.

Specific- the thorax/arm curves for the pro but likely disruption for the amatures. "IF" #4 is "thrown off the chest" I would expect to see it in the pro curves. I have had some ideas on this subject but first I would like to hear your opinions.
