The flight characteristics of a specific disc golf driver, the Felon, manufactured by Dynamic Discs, are quantified by a series of four numbers. These represent speed, glide, turn, and fade, respectively. For example, ratings of 13, 5, -1, 3 would indicate a very fast disc with significant glide, a tendency to turn slightly to the right (for a right-handed backhand throw), and a strong, predictable fade back to the left at the end of its flight.
Understanding these metrics allows players to select discs suited to their throwing power and intended trajectory. This data is crucial for strategic course management, enabling players to navigate obstacles and maximize distance. While disc selection relies on individual throwing styles, these standardized numbers provide a common language for discussing and comparing disc performance. This has contributed significantly to the growth and sophistication of disc golf as a sport.
