I never use to think much about carry down as it didn’t seem to affect my game. But since I started bowling on synthetics regularly with their big back ends, I cover more boards than I use to.
If carry down effects all balls an equal percentage, say 10%, then someone who hooks the ball 20 boards might come up 2 boards light but someone who would only hook the ball 5 boards would only be ½ board light.
But is the affect linear or might it be exponential? If exponential the affect would even be greater to the bigger hook.
In many cases these two types will be taking different lines to the pocket but they end up sharing the same breakpoint.
Who does carry down affect more the big hook or little hook or is it the same to both bowlers?
