When you are out stumping, do you shoot just one arrow?
If so, it is just a concentration thing.
I cannot shoot more than one or two arrows with the accuracy I want, before retrieving them.
The break you get while you walk to pull your arrows gives you time to rest and recharge so you can concentrate to the FULLEST again.
Whenever I shoot broadheads, I always shoot just one arrow so I did not damage other arrows. Before long, realized I was a better shot with broadheads than field points. THEN I realized, it was my concentration level staying so high by shooting just one good shot.
