The Derivative Gain dampens the rate of change of the error, decreasing the throttle response as to not accelerate too rapidly toward the target speed, and therefore reduces the chance of overshooting the target speed. A higher Derivative Gain will take away more throttle, and thus Proportional and Integral Gains can be higher before the controller becomes unstable. However, higher Derivative Gain when close to target can cause subtle hunting (and consequently some motion sickness).

Values in this table will change depending on your speed units selected in Preferences.
