When it comes to missing putts, the real culprit is improper face angle. According to research by sports biomechanics professor Sasho MacKenzie:
"Golfers have only a 0.7-degree margin of error with their putter face when attempting a straight 12-foot putt. If the face angle is open or closed by more than 0.7 degrees, it results in a missed putt. Surprisingly, stroke path has a minimal impact on making the same straight 12-footer. So, focus on keeping that clubface square!"
