No, that's not what I suggested; not at all.

Not exactly, but close to what I am asking about.   Not "greater ground 
support" in absolute terms but in efficiency of return relative to original 
input. 
  And, yes, I would have thought that the team would look very closely at 
that and not focus on metabolic cost of swinging the legs; especially since 
maintaining ground force production is the concept that goes to the heart of 
the 
Weyand hypothesis for running mechanics conducive to higher velocities (as it 
has been explained to me and I understand it.)

This "report" (as yet unpublished) seems to be contrary to the very basis of 
the Weyand hypothesis unless there are mitigating circumstances specific to 
the prosthesis.
