Since this is a shooters forum, and not a bowhunters forum, the 30-40 yard ranges should probably be considered as medium range. I often shoot 3d along with the compounders. That means shooting up to about 50 yards or so. Although some traditional archers may be good enough to use an instinctive style for medium range shots, I find it essential to develop an aiming system. For the long range, 50-80+ yards, it seems important to accurately judge distance and to have an aiming system.
