I have played in a number of matches where the middle player and shooter have swapped roles temporarily during the game. This has allowed the shooter to point a few boules, helping them settle into the match, focus on their landing spot, and develop a smoother arm action and rhythm. They would still take the occasional shot when required. After a few ends, we switched the players back to their original positions, and without fail the shooter's accuracy and hit rate were better than before the change. In my experience, , what little it is, giving a shooter the opportunity to point for a short period can be an effective way of improving confidence, rhythm.
