Funny question.. Just Tuesday night in League I was shooting next to a guy who was shooting an older model bow. It was like a 22 rifle going off. He was shooting 80 lb draw wieght. I asked him about the noise, he said deer don't have a chance to jump. Whether I believe him or not isn't the issue, his thought process was the interesting part.
I also learned to wait till he shot to draw..that thing'll scare the bejesus outta you!
Here are the numbers, I got them from University of Wisconsin Study.
Shoot 200 fps, deer jumps string. A person would have to shoot over 700 fps to hit the deer. A deer can jump his string.
For target all the speed freaks thing it helps, and it does. If you miss judge a target a little a flatter shooting arrow can help. The opposite is if you jerk a little a faster bow hurts you a little more. Like my uncle, it goes both ways lol
