Not about the Follow up shot, it's about a deer jumping your string. IMO

A deer can jump an arrow 180 FPS, that same deer would have jump the arrow if it was travling at 330 FPS,400 FPS, 500 FPS, 600 FPS, and at 700 FPS you hit it
So at an animal the is killed on average of 17 yds, why does 300+ FPS bow matter.

Now Elk is another story
