I strive to shoot as perfect at the range as I can bc its a controlled environment. When I am in the field under stress and tired I know, in my case, my shooting suffers a little. If you're at the range shooting 100% maybe you'll shoot 80% in the field. If you start off at the range satisfied with an 80% what might it go down too in the field? I try to shoot the limit of my tool. If it's sub inch gun my goal is sub inch.
