The amount of automatic shift is calculated with speed, and the amount of shift is
limited to 60% of the range in use. For example, if you set the shift speed setting
for 15 knots and the ship is running at 10 knots, the amount of shift will be 40%.
The formula for determining shift amount is as shown below.
