Target archers tend to be more concerned about it than hunters shooting at close ranges.
I agree, Straightarrow, but I think that's the wrong mindset for hunters. Target archers have plenty of time to make sure their form is right on. They're always using their very best stance. They can let down several times before taking the shot if stuff doesn't feel right. Hunters don't have those kinds of luxuries. They should not be hunting with a 3D bow, but that's exactly what the vast majority are doing.
A hunter doesn't always know exactly what direction he will be shooting. He might have to twist around to the left or right to get on target. He might have to kneel or squat to get clearance. If he's shooting from a treestand at a close animal, he'll be bending over from the waist. He might have to lean around a tree trunk. In short, it's a rare occasion where a hunter can use pure target shooting form. And then it's very possible that he'll be cold, wet and tired, with the adrenaline going, heart pounding and hands shaking. Your concentration should be only on the animal and shot selection, not on the equipment. When the animal is right there in front of you, that is no time to be overly concerned with getting all your points of form lined out before you can take the shot.
For those reasons, I believe a forgiving bow is far more important for a hunter than it is for the target archer. When you've got a bow that forces your hand to naturally assume the correct grip and will shoot very close to point of aim regardless of minor form issues, then you've got a hunting bow.
