A Deer is 20 yards/60 ft from the hunter. His arrow upon release will be traveling lets say 220 ft per second. Not super fast for a bow these days but somewhere in the middle range. Like it was said earlier sound travels at 1100 fps.
Upon release of the string the sound gets to the Deer in .0545+ sec. The arrow gets there in .25 sec. That gives the Deer .195 sec to drop down as they do allowing the arrow pass over it’s back then bolt or jump away. That is a fith of a second. It still happens but Im sure not as offen as it did when the average arrow speed was slower.
Now I don’t think the Deer knows to drop down to avoid the arrow. It is just a natural part of the reaction and physical process of the bolting away from danger.
How long does it take a line drive hard ball to travel from the end of the bat to the pitchers mount and have a pitcher get his glove up and catch it? I think Deer are faster that even a pro ball player. JMO
