# Parameter

Each horse has five different parameters: speed/stamina/guts/temperament/stability.

Speed: This status affects acceleration, cruising speed, and fuel consumption. The higher the speed, the faster the horse can run, but the lower the fuel consumption.

Stamina: Stamina affects total energy and cruising speed. The higher the Stamina, the longer the distance the car can run.

Guts: This status slightly affects cruising speed, total energy, acceleration, etc. The higher the value, the more competitive the driver is. The higher the value, the easier it is to win a race.

Temperament: Temperament affects competition, acceleration, and fuel consumption. The higher the value, the more stable the horse tends to be.

Stability: This is a status that affects breeding. The higher the stability, the more stable the foal will be on average. However, when a horse with low stability is bred, it is rare that a great horse is born that greatly surpasses the parents' status.
