A birdie is one of golf's most satisfying accomplishments — completing a hole in one fewer stroke than par. On a par-4, that means finishing in 3 strokes. On a par-5, 4 strokes. Birdies require both accurate ball-striking to get close to the hole and confident putting. The average recreational golfer makes fewer than one birdie per round. With GOATY AI coaching, students consistently report seeing their first birdies within weeks of fixing their primary swing fault.
