I am very happy with my 955 Solar. The gps is very precise and the rest of the metrics seem to be too. But I have a doubt, I haven't used any Garmin device in two months, but I have been training continuously. Now the 955 when I start using it tells me that I am overtraining. I imagine that with time this will be fixed? I understand that it's because I don't have a history of the last few weeks and suddenly see the level of training I have. Has anyone had that experience? Cheers
