A given set of prints could be produced from long air time and more moderate speed, or short air time and more extreme speed.
I expect a range of possible speeds is known for human locomotion for any given distance between steps, but it won’t be any exact number.[/quote]
Yeah, I would expect a generic model formula that they just plug in for stride length.
I was just throwing out there physical ways of calculating it. And when I was talking about calculating air time I was including impact conditions, not simple projectile trajectory.
