Warning: Do not try to use these sample calculations to mark an actual track! These calculations are correct only for a track with the exact dimensions shown.
The drawing and calculations below are for a track with the same dimensions as the sample calculations example. Note the smooth juncture between the approach to and return from the water jump and the track, and the gentle curvature of the paths. Curvature is less for paths which join the track closer to the beginning and end of curves.
