Some folks may know this, but, for those who don't, try it out! Let's not dwell on the why, here is the how to.

Take a look in the cup, one of the edges will be scalped(frayed). The side of the cup not frayed is the side you must enter the hole on. So no matter how much break you read, the ball must always enter the hole on the opposite side of the scalped area.

When standing at your ball, if the scalp is left, enter the hole from the right.(right to left breaker)
If the scalp is on the right, enter the hole from the left. (left to right breaker)

Low and behold if the scalp is centered it means the putt is straight for the last foot and 1/2.

Gift it a try and you will make more putts. Amount of break is always a guessing game, this will help you guess better.
