Sarosh, that was the exact analysis I just did and was about to post, I got ~4% for a 24" sensor distance(~61cm).  I agree that the card speed is extremely fast for a throw, from what I've seen elsewhere, around 60mph is the "world record".

Short clip of a stone flying towards the camera.
I used my 18" Lahun-style sling
I calculated the average velocity over 40m to be ~50m/s.

Daaang!  What was the approximate weight of your ammo?

I don't know exactly, but I remember it was vaguely similar in size and shape to a 120g stone I picked up at the same time. Not more than 150g.
