When I watched this amazing video again I think it disproves another theory I've considered. Ever take a 3D shot where you new at the moment you released that the sight picture was slightly off, you plucked, etc. and the shot still found the 10 ring? Not that it happens all that often with me(lol), but often enough I've wondered if our hands are far less steady than we think and the mind is constantly "compensating" for our flaws by making subconscious, subtle corrections in the pressure of our bow arm/hand right up until the arrow clears? Nah, maybe not. If it were so, with all of the minute, snaking oscillations the camera is revealing with those arrows that bow hand should be waving all over the place. I detect some "flexing", but it is pretty much "dead nuts" solid. Oh well, it was a nice thought!
