I am surprised that no one has mentioned a thing called "Target Panic". It really doesn't matter if it is shooting too much draw weight oranoveraggressivecam, the end result can be the same.

When fatigue sets in your brain starts to tell your muscles that it is time to dump the string pronto. As you are struggling to float the pin and make sure the sight picture is correct before you release the battle between the "ears" turns into an all out war. This can start a whole chain reaction of negative habits that result intarget panic which can be carried over to the field.

If a guy can avoid this pitfall I think he is much better off. Been there done that....
