Just got the new 520 last week and on only my 2nd ride I experienced something strange. Yesterday at about mile 20 the elevation jumped up to 6000' and the gain showed 2405' and never changed for the rest of the ride. I think this happened at a point where I stopped the counter to rest at an overlook and the started it back. I would think this was just a random odd event but it was just my 2nd ride. Should I be using the auto-pause function or should the unit perform normally just by stopping and restarting manually? I attached the profile and you can see where it jumped up and then just slowly went back down during the ride. It was correct until this point but it never showed a gain after that. The track with the miles was also correct. Any suggestions?
