The authors benefited from feedback during presentations at Yale University and the Research in Economics Using Sports Data Conference at Central European University. The authors used generative artificial intelligence tools (Claude and ChatGPT) for language editing. The authors also appreciate the time that the golfers and coaches spent interviewing with them. The authors are especially grateful to Kurt W. Rotthoff and Todd McFall for providing additional information on groupings from 2004 to 2013 based on tee times from ShotLink data. The authors also thank Department Editor Sameer Srivastava and the anonymous associate editor and reviewers for their constructive feedback.
