"Point Shooting" as it's called here is, I would say, the same as "Instinctive Shooting" of a long bow.
Anyone can get better at it with practice but some guys got it, some guys don't.
Have you ever seen the guy shoot Aspirin out of the air with the long bow? Practice all you want, MOST of us will NEVER do that.
I can definitely see the reasons to practice but I wouldn't want to rely on it unless it was do or die.
Still happily answering to the call-sign Peetza.
You do not HAVE a soul. You ARE a soul. You HAVE a body.
He is no fool who gives what he can not keep to gain what he can not lose.
