I'm fortunate to have large back and front yard to shoot. When I brush hog the last 3 acres, I can shoot up to 100 yds. It's fun arching arrows out there...
However, the pics below are taken from my deck. I can shoot 10/20 up to 60 yds. I pick out anything, like bare spots, dandelions or I throw out small foam pieces ALL AT UNKNOWN DISTANCES. I don't know how far any "target" is in my yard...don't know..don't care.
Even my beat up 3D turkey taret "Tommy" sits out there...probably close to 40 yds....never paced it off. You become a better shot not knowing and relying on your shooting instincts and ability to make the killing shot. By shooting distance and becoming pretty proficient will make you a deadlier shot at the closer ranges.
Bare spots...concentrate and place arrows in all of them. The farthest one is uphill, assume it's close to 60 yds
Close range shots...pick and shoot.
I usually throw some small foam pieces out to the left of Tommy. Bearing down and concentrating on my target.
