Since the upgrade to version 12.20 I notice that even while the vertical speed is showing 800 metres/h or more, on steep slopes I regularly see a slope of 0% :( I don't often ride in areas with such hills so have not been able to get a better picture of exactly in what circumstances it happens, and understandably when I am on a 20% slope, not much oxygen gets to my brain. I did see that one improvement in the update to version 12.20 mentioned "Updated precision of the Grade data field to whole %'s." now I have recently ridden in the hills again with slopes of up to 20% and now I have version 12.60 and still I see 0% showing on steep slopes
I’ve encountered this myself with the Garmin Edge 520 I’ve noticed 2 things:
1) It seems when speed is below 10km/h (common on steep grades) gradient reads 0%. It must connected since when descending down the same hill it reads the proper grade.
I have the same problem. I am using highest sampling rate available (not smart sampling). I saw a comment above about loading different grade fields from Connect IQ. How does one do that?
