I hear ya, Dan.....but imagine shooting at a brown surface with no distinguishing marks. LOTS of times that's what we're doing. I see nothing wrong with trusting a hunter when he tells me he's taken into account the angle of the arrow.......and his pin is placed on that brown surface with that in mind.

ESPECIALLY since it's a known fact that the angle will CONSTANTLY change until the moment of truth.

It's one of those "pat" answers that I just don't like. Another "constant" that is everything but.
