If you draw a straight line from your nocking point to the 20 yard target, your broadhead/arrow point will not be in that straight line.
OK. So.....taking this a bit further......the the arrow is NOT "level" if you were standing on perfectly level ground......to the ground????
In other words.....if we drew a line from your nocking point through your arrow tip......would this line be perpendicular to the ground (again....assuming we were standing on perfectly level ground)?
I think it would be relevant to the raising or falling of the barometric pressure.And the direct perpendicularly arc free straight line to the equator.
