I've recently purchased a forerunner 50 but I'm a little disappointed
with the accuracy of the watch, it seems to be loosing at least a
second a day - Is that usual or am I expecting too much? Also after
doing a couple of runs and checking the route on gmaps I had to
recalibrate at 86%. Is it possible I've got a faulty watch because
garmin say it should be 95% accurate out of the box?
