Somehow I knew this would come up. Here are the numbers:

A bow shooting at 280 FPS a deer moving at 2 MPH:

At 35 yards a deer can move a little over one foot by the time you shoot and the arrow gets there.

At 12 yards a deer can move a little over four inches.

Remember I am calculating this based on constant speed (deer and arrow), of course the arrow will slow down a lot by the time it gets 35 yards. So the 1 foot measure will be greater.

If you need the calculations let me know.
