The logic is that if the deer hears the twang of the string, the sound is traveling faster than the arrow, it will need to put its forth food down, then bend all four knees, before it can spring upNever heard of such an idea.
Ive made walking deer stand still, running deer stop, and Ive made obscured deer stand up and expose themselves. I'm not much of a clay buster I don't trust myself to hit a moving targetBut a lot of stopping the deer with noises (i.e. making them alert) and shooting at overly long 30-40y distances in US forums etc. Acts of desperation I'd say, based on local seasons and rules. And I'm not opposed of people shooting at whatever distance they've practiced enough. But the middle distances are problematic since they're still in "immediate danger zone" but long enough that fligh time is substantial. Combine that with purposefully setting the animal on alert, and the recipe is ready...
