I don't practice as much as I should. When I do practice I try to have quality practice over just flinging X number of arrows. When I don't have the time or inclination to go outside and shoot I will shoot blank bale inside. When I do practice outside I will shoot one arrow at a time and vary the distance with each shot. Either doing a walk up or walk back from my target butt. Maybe once a week I will go out and shoot my Mckenzies I have set up. Then for practice I may shoot a local shoot once a month to prepare for the national level shoots.
Shooting on this type of schedule allows to keep focused while shooting(not burnt out from shooting), it forces me to make every arrow count(just like in a tournament or hunting situation), and makes me work to be as good on the first shot as you want to be on the 40th shot.
