30 yards is a very long distance for most traditional archers. As stated in numerous previous posts, all form faults are magnified greatly. Yes, it is more difficult to maintain focus and to pick a small spot. (Hell, at 30 yards I have difficulty seeing the deer, much less pick a small spot). That is a bit of a joke, but it is hard to do, especially as I get older. The average archer usually doesn't practice enough to really develop the muscle memory. For every shot we make at 30 yards, most of us have made many hundreds of shots at 15 -20 yards. However, skill at longer distances is possible. I practice the long shots knowing full well I never intend to take such a shot in the woods, but it is true that long distance practice does tend to make the closer shots seem easier.
