And, we're back to where we started -- defining the term.
As I (and I think others) are using the term, I mean that if F1 releases the ball such that it's instantaneous /initial vector is parallel to the ground, the ball will never be farther from the ground than it is at it's initial point. In addition, the ball's distance above the ground at any position will be (a) less than at any point prior to that position and (b) greater than at any point after that position.
I also think that everyone agrees that if two balls are thorwn at the same initial angle relative to the ground that (all other things being constant) (a) the faster ball will "fall less" over the same distance and (b) the ball with the greater backspin rate will fall less.

When I see a golf ball on a line drive 20 yds off the ground for 100 yds and then rise to 40 yds before gently landing 280 yds away, notice I saw it I didn't hit it, is that just a function of the demples?
