The four numerals representing speed, glide, turn, and fade, assigned to a specific disc model by its manufacturer, quantify its aerodynamic characteristics. For instance, a disc with values of 11, 5, -1, 3 would be categorized as a high-speed, stable-to-understable driver with moderate glide and a predictable fade.
Understanding these quantitative representations of a disc’s flight provides disc golfers with crucial information for selecting the right tool for a specific shot. These values allow players to predict flight paths and choose discs that match their skill level and throwing power. This system enables strategic course management and facilitates more effective shot selection, ultimately improving player performance. Historically, these ratings have evolved alongside disc technology, providing a consistent framework for evaluating and comparing discs across different brands and models.
