I religiously practice out to 40 yds on a daily basis. Roving and stumpshooting at any target at unknown distances will sharpen your skills on how to judge distances.
In my backyard I'll pick anything out on the lawn..a leaf, sunspot, worn out patch of grass, a root etc...how far? Don't know...don't care. I shoot my hunting bows with the arrows I'll be bow hunting with. So I know exactly where to aim and if I miss...my split vision method allows me to make my adjustments.
You need to learn how to judge distances, it takes time and practice. Then knowing your bowhunting setup when shooting at those distances whether it's close or far. If you can become fairly proficient at longer distances (not saying your going to shoot that far at deer), that concentration should carry over to those shots that are within your "Effective Shooting Range".
