Why do they call it "Jumping the String" when deer are actually ducking the arrow?

Kinda stupid.

Anyway - If anybody is bored and mathematically inclined, it would be cool to see a grid with various ranges and speeds (FPS)- accounting for the speed of sound (1128 fps) - to establish exactly how much reaction time a deer actually has to react and duck the arrow at each range at each respective speed.

What I wanna know is the time between the deer hearing the sound of the bow going off, and the arrow's actual impact.

Speed 100 150 200 250 300 350 400

Range
10 (30')


20 (60')


30 (90')


40 (120')


50 (150')


60 (180')
