Nope. I am not sure how the data is relevant in the slightest degree. But thanks for adding to the discussion anyway.
Seems pretty logical to me. If the BG was approaching with the gun pointed directly at me, I may want to hit him in area that would cause the hand muscles to relax and possibly drop the gun - not in an area that would cause them to contract (& possibly pull the trigger). But that's just me.
Again - I am not saying that I could be that precise in a stressful situation
