Whats the accuracy of the recorded tracks?
The accuracy of the recorded location data depends on your GPS receiver and your surroundings. The GPS device needs a clear view of the sky to receive the signals of the satellites. In cities with large buildings, the accuracy will be lower than on the countryside where nothing disrupts the GPS signals. The checkpoints do not have to be hit exactly, but instead have a tolerance radius to circumvent the accuracy problems of GPS. RealReplay records your position every three seconds to limit the amount of data.
