What would you say is a safe number of times to shoot at a target before fatigue starts to set in? In other words how many shots do you take when practicing? I usually shoot 4 arrows at 10, 20, and 30. But by the time I get to 30 yards I don't know if my sight is off or I just can't stay steady enough. When I shoot, is it better to shoot from 1 distance only, then stop for a while and then try a different distance the next time? Or am I doing it right checking all my distances at once?
