Lost Arra,
When we stump shoot, we often shoot at a mark less than 20 feet distant that requires the archer to 'thread the needle' thru holes in the foliage, between saplings where there is 4-6" 'alleyway' to the mark..and the mark is small..the size of a tennis ball.
Often the shot requires the archer to kneel or evn sit to see the mark thru the eye of the needle..

One soon finds out about his 'form' loose, strength, concentration and the proper matchup of arrows to bow..brace height etc on such shots..and it's less far to retrieve the arrows too.
It's ALL good practice..:) Jim
