Find the biggest slope inside the middle third
Read the middle third of the putt, not the exact center. The speaker says on a 20-foot putt that section runs roughly from seven feet in to 14 feet in, and the biggest slope there is how much the ball will break. If it's steep early, take the read about a third of the way in; if it's steep later, about two-thirds of the way in.
