Then the putt breaks 14 ineh8sc230;not 4 inches. You ALWAYS aim a putt where you want it to start. The better plan is for amateurs to become more familiar with what 4 inches is. At 30 feet, most amateurs line up 2 feet left or right for 4 inches. When you put the size of the cup to them as roughly 4 inches, their perspective changes. At 10 feet, a person putting has 1 degree of variance left or right and they can still make the putt. How much is that? About 7/8 of a millimeter open or closed.
