The new way to adjust scores with Equitable Stroke Control sets a maximum number that a player can post on any hole depending on the player's Course Handicap. 

If a player starts but does not complete a hole or is conceded a stroke, he shall record for handicap purposes the score he most likely would have made. The most likely score consists of the number of strokes already taken plus, in his best judgment, the number of strokes the player would need to complete the hole from that position more than half the time. This number may not exceed the player's ESC limit, defined below. This most likely score should be preceded by an X.

For Handicap purposes, you are required to adjust your hole scores (actual or probable) when they are higher than your maximum number you can post. 

If a player does not play a hole or plays it other than under the Rules of Golf (except for preferred lies), his score for that hole for handicap purposes shall be par plus any handicap strokes he is entitles to receive on the hole. The score should be preceded by an X. 

ADJUST YOUR SCORES WITH
EQUITABLE STROKE CONTROL

Scan your score card for any hole where your score (actual or probable) is higher than your maximum number. 

Reduce these higher scores to your maximum number for handicap purposes.

Post your adjusted score.
