I was confused with the traveled distance vs jumping time plot. Intuitively there should be three points at which the traveled distance is zero: at the two max swing heights, and at the min swing height (assuming your legs touch the ground at min swing height). However the plot seems to only show zero traveled distances at min swing height? Or did I misunderstand the plot?

When you jump at the max swing heights you travel l*sin(phi). At these points you jump with zero velocity, however you've already moved from the starting position (phi=0)

  A ballistic trajectory is a 45° angle isn’t it? But that’s significantly short of max distance X.
