I want to thank again all those you were kind enough to help! Here are the
responses to the question posed:

1. I believe that data is in David Winters book
Biomechanics and motor control of human movement, 2nd ed Wiley pub.
Kevin McQuade PT,PhD
University of Maryland

2.Although it will not provide you with COM/COP data, the following
article might be of interest in understanding the timing of forward
COM progression and it relationship with the timing of the center of
pressure during gait:
