Thanks for the correction…that solves more than the occasional difficulty from past and current in terms of, from the athlete “…just does not seem to work…”, but in a way adds another problem.
It is an aside from this thread but what I mean is that take off angle/lean now has to be added to the list of things that require consistency (it is an aspect I have often talked about but rarely, if ever, in terms of consistency).
Since, unless I am misinterpreting again, a given shape of parabola at a given athlete velocity will only result in a particular touch down point if the COM starts that given parabolic path at the “exact” same vertical and horizontal point (relative to the hurdle say)and with the athlete taking off at the same lean angle. And, since the athlete hurdling is rarely at the same velocity (they are either accelerating or decelerating relative to some velocity, “X”) each parabola should be different (i.e. each flight of hurdles). Or, if the shape is the same, the flight time has to change?
I know that is just restating and its not really “another problem”, but still correct?
