If I'm making a guided route the instructions can change with each lap (or the return leg), the same point or nearly the same point may be seen multiple times. The instructions change with each lap, the "time" of the waypoint is to help job the memory of the route creator (lets see.. lap1, lap2?, North, South?). I suppose the sequencing of the file names in the camera could help but, time nails it. OH NO! Can you see what's next? THE TRACK POINTS MAKE A VECTOR! LOL
