Foot position
I did notice that Rhys had not given enough thought to his foot position. As seen below, Rhys adapted a rather square and open stance, which did not put him in the best position to move efficiently to and through the targets. He was unable to finish off the shot as he was out of balance.
The red arrow indicates the direction Rhys’ feet are set to kill targets; those of you who play golf will understand this concept. This was completely out of place as his feet needed to be set further round to the left. By making this change Rhys was able to make a more bio-mechanically efficient shot, which made it easier for him to repeat the same move again and again. Despite the fact that the foot position for the first target is more central than that of the second, Rhys made the decision not to move between shots and instead set his feet for both targets in the same position. Usually this is not acceptable, because the first target requires such little horizontal movement, but in this case it was a good decision, allowing the shooter to focus on nothing else but the bird.
I hope that you found this recap useful and will continue to follow this series.
