Your grade gauge will increase or decrease based on your performance in Standard Races and Gold Races.
Once this gauge has increased to a certain amount, your grade will increase. If this gauge decreases to a certain amount, your grade will decrease. The higher your position at the end of a race, the more your gauge will increase; the lower your position, the more the gauge will decrease.
・Players with a grade of S or higher will not gain or lose grade when playing Standard Races.
・Races via With Friends or Others Nearby have no effect on your grade.
