In general, a vessel with fast turning rate will require a lower value.
This may be adjusted according to vessel speed. I.e. Low speeds may require
a higher value, as the vessel will respond slower to larger rudder movements
at lower speeds.
NOTE: If the vessel is understeering and taking a long time to get back on
track, increase this value. If the vessel is over-steering or overshooting and
making hard turns to stay on track, decrease this value.
