I did a quick calculation though: It takes about 20 frames for a ball radius to travel across the screen. If ball radius = 2.35cm (.0235m) then at 70,000 frames per second would put this ball at about 82 m/s which is approximately 180 mph.
This is super rough and the ball diameter information I found varies quite a bit. If anything it seems that the speed in the description is ballpark accurate.
