RE: String Jumping Distances-"Boo Theory"
I decided to give some of the figures used in the article for those who don't have it.
Speed of sound - 1085 fps
Time for arrow to go 20 yards at 230 fps - .275 seconds
At this speed it takes .056 seconds for sound to reach the deer at 20 yards - leaving .219 seconds for the deer to react and start dropping.
Reaction time for deer after they hear the sound - .05 seconds - this leaves .169 seconds to drop before arrows arrives.
Deer will fall at a rate based on the accelerarion of gravity, which is just over 5 1/2 inches in this senerio.
Increasing the speed to 280 fps and leaving everything else the same will produce a drop of 2.75 inches.
Using these figures, at 5 yards the arrow has hit the deer before he can even react, without even taking into account how far gravity could make him fall.
Once again, I'm just relaying information given in a very well written article. The only debatable figure is the deers reaction time and the figure they used was so fast, that even eliminating reaction time wouldn't have made a huge difference. The real difference comes at longer distances. In this article is pointed out that the same deer at 30 yards would have dropped 16 3/4 inches with a 230 fps arrow.
