Justin Rose has one of the most repeatable swings thanks to his repeatable hand path throughout his swing. There's no exaggerated loop at the top. Instead, his hands stay remarkably on plane as he transitions from the backswing into the downswing.
Then look at his Club-Hand Gap—a tracker that measures whether the club travels too far inside or outside the hands throughout the swing.
Justin stays in range here, too.
The combination of an on-plane hand path and an in-range Club-Hand Gap creates an incredibly repeatable delivery—and helps him produce a consistent strike time and time again.
No exaggerated loop. No unnecessary rerouting. Just an efficient path back to the ball.
