Deemples scoring platform doesn’t allow you to key in your own scores, making it the fairest handicap system available. At the end of your game, you can key in your playing partner’s adjusted gross scores after applying equitable stroke control, but you cannot key in your own scores.
Once you have at least 5 scores submitted by others on Deemples, the app will then calculate your handicap index and revise it every time a new score is submitted. This allows you to have a most trusted, peer-reviewed, peer-inputted, peer-approved handicap which you can apply to all your golf games.
Remember, the Deemples handicap is not sanctioned by any local or international golf association, so it won’t be valid to use for official tournaments. But you may definitely use it for your personal calculations, and hopefully one day everyone will learn to embrace the fairness and methodology of the Deemples handicap system.
