I had a rather positive experience with the new software. Did the software update, powered completely off and on and when out for a run. Started of with 7 satellites, finished with 6, got no idea how this was during the run as I did some tempo's. I think the results are very good as of distance as there is a 0,9% difference. Which by the way does not mean that the Leikr is 0,9% off because I would not claim that the Garmin is 100% correct.
As I am always reading about tracks being jaggery, therefore I looked in detail to the routes on Endomondo and on the Garmin site and noticed that both watches have the same 'hick-ups'. So I would say that has something to do with satellite reception and not with the watch itself.
Garmin Forerunner 620: 14,27km
Keep up the good work. With these differences I can and will use the Leikr.
