Mean group dendrograms of the practice group (n = 12) for the golf putt at (A) pre-test and (B) retention-test. The numbers on the x-axis relate to the BAC number, the numbers on the y-axis display euclidean distances. The lower the link between related BACs, the lower is the euclidean distance. The horizontal dotted line marks dcrit for a given α-level (dcrit = 3.41; α = 0.05); links between BACs above this line are considered unrelated; horizontal gray lines below BAC numbers mark clusters. BACs: (1) shoulders parallel to target line, (2) align club face square to target line, (3) grip check, (4) look to the hole, (5) rotate shoulders away from the ball, (6) keep arms-shoulder triangle, (7) smooth transition, (8) rotate shoulders towards the ball, (9) accelerate club, (10) impact with the ball, (11) club face square to target line at impact, (12) follow-through, (13) rotate shoulders through the ball, (14) decelerate club, (15) direct clubhead to planned position, and (16) look to the outcome [Reprinted from Frank et al., 2013, with permission].
