Your first round will be used to establish your handicap. It will be entered five times to set your handicap. Each subsequent round will replace one entry of the first five. Gold Tee participants must be a PSMGA member in good standing to win the hole-in-one pot of gold payout.
The course rating is subtracted from each of the 10 best scores and the results are averaged, and then multiplied by 1.0. Delete the decimals and you will have your handicap. If fewer than 20 scores are available then a percentage of the scores are used. See USGA for further details.
