Well, 5 meters is way too short for distance. Average gps accuracy is around 
15 meters so you'd want distances higher than that. If you do what it sounds 
like you're doing, putting in all points as checkpoints, you'll have a lot 
of output and the program probably won't be useful for much else. You can 
only have about 1000 checkpoints before the program runs out of memory so 
trying to store everything as a checkpoint just won't work.
