Because a handicap is a measure of your golf potential, not all of your golf scores are used in the calculation. In fact, only the ten "best," of the last twenty, scores are used (if you have less than twenty scores, less than ten are used to calculate your handicap). The gold stars denote which scores are used in the handicap calculation. (Note that these might not be the lowest scores, as scores are adjusted for the difficulty of the course). You can find out more about stars and other elements on the scorecard by clicking on the question mark button at the top right of your scorecard.
