Sur Tradtalk un post intéressant sur les groupements avec un exercice assez dur pour les nerfs mais qui vous rend d’un coup humble et plus solide à la fois.

“Make an hall”
Most of us can shoot very good groups,”SOMETIMES.” The thing is that being human we tend to forget the fliers.It’s the archer that is the most consistent that will bring home more animals and awards.
Here is a game a world class archer told me to try.Make yourself a circle on your target whatever size you want.Let’s just say softball size.Start at 5 yards and shoot three arrows into your target.Don’t move back any farther untill you can shoot 10 three arrow groups into the spot without a single arrow out.Then go to 10 yards and do the same thing.Then 15 and so forth.If at any time you miss even one arrow,start all over.See how long it takes you to get to 20 yards.Give it a try,it’s a humbling experience.
