Mobow,
I think the bottom line definition for everyone, is all about acceptance of risk. If no one was worried about any risk what so ever, they’d take a shot as far as they could see.
BUT, you start whittling that range down by adding risk. Some risk ruining an arrow without getting meat in return. Some risk a long night on a wild goose chase blood trail. Some risk the fear of having their ego knocked down a peg with a miss. Throw in a HUGE buck and some loose all fear of risk for that one shot that MIGHT find its mark.

People can give groups & what ifs till they are blue in the face, but the bottom line is risk. Do I want to risk a wounded animal, that I may or may not find and a lost/trashed arrow that costs me $20 to replace. That is why some people will fling at any distance, while others who may be more capable of a shot, choose to shoot at a closer range.
