See I don't agree. You are FEELING shock AFTER your arrow is gone, but that shock actually occurs upon release, what do you think causes any noise at all? it's the vibration. You are talking about anticipating the noise from the shot. Noise is caused by vibration. Vibration causes loss in accuracy. I thought that was pretty commonly known.
Agreeing or not doesn't change the fact that the reaction can't occur until the action has happened. The action in this case is the string going through its firing cycle. The string and limbs overshoot the static state as the arrow is propelled off the string, the string and limbs thenoscillate back and forth aound their static position until they come to rest. What you're feeling as hand shock is that oscillation. The arrow has to be gone before the oscillation begins because the first stroke (wave) in the oscillation is the one that launches the arrow. The amplitude of the oscillation is determined by the amount of latent (not transfered) energy in the system. Likewise, the noise isn't generated at release it's generated by the expulsion of that latent energy in the system that occursat the time the arrowleaves the string. Similar occurance with a rifle, the report isn't generated at the time the trigger is pulled, it's generated when the bullet and gases exit the bore.
If hand shock caused poor accuracy no compound shooter would have ever killed a deer 15 years ago and no longbow shooter would ever hit the broad side of a barn much less an aspirin tossed into the air.
