The numbers were provided by Transrapid, the builder of the China maglev. The numbers are the height of the outside of the track from zero from the inside of the track instead of using angles. Most of the public can understand this better than angles. It gives people a better feel for how much a track must be banked to allow vehicles to go around a curve safely. The higher the outside the faster a vehicle can go around a curve safely.
