TSD (Time/Speed/Distance) rallying, also known as regularity rallying, is a safe, enjoyable but exacting motor sport that fully puts to the test your car's reliability and responsiveness, a driver's ability and a navigator's accuracy in interpreting specific route instructions. A rally is a competition in which cars individually leave a starting point at a carefully recorded time, and are instructed to accurately follow a designated route while maintaining specific various rates of speed along this route.
DISTANCE = TIME X SPEED
TIME = DISTANCE/SPEED
SPEED = DISTANCE/TIME

User can display Target Times in any Waypoint by Drag and Dropping TSD TIME Icon into any Waypoint. This can be used to create helpful practice Roadbooks (Example: First Stage of a TSD Rally) or to offer participants a hint of correct time along the way.
Distances and target times are calculated and displayed to three-decimal-place accuracy (.000) in the roadbook, so crews can hold precise average speeds.
