I've been standing still for the last 75 minutes and the F5X says I've just completed my floor target for the day!
Now I have a sports watch that doesn't track steps right, doesn't track floors right, doesn't track HR right, doesn't show distance to destination while navigating. And these are the bugs Garmin has confirmed knowing about on this forum as being widespread. I won't even go into individual cases. If didn't want these basicist of things I would've bought a £5 Mickey Mouse watch not a £850 frustration black hole.
