Hi,
I am using a Garmin Instinct Solar to track my running activities. However, the elevation data unfortunately seems to be false by a good percentage (giving 400m ascent instead of 200m).
I am suspecting that instead of using the GPS tracking data to calculate elevation data (as does the application Strava used in a mobile phone) Garmin uses the integrated barometer to do so.
In my activity, it looks like (that's my only explanation for it) in the middle of activity, Garmin did a GPS calibration for the Altimeter and I climbed 100m in 9 seconds (beating Bolt vertically). Even then, the elevation data does not match when I follows my running trajectory on the map (which itself is accurate).
I am living in a mountainous region and total ascent is an important part of activity info, with such huge inaccuracies, it is preferable to not to use Garmin watch but go back to the old method of carrying the phone and turning on a sports application (that's a pity as most of you would agree, this is precisely the reason why we buy such watches).
My question is: how to fix this issue? Is there a way to use only GPS data to calculate the ascent/descent data for an activity (i.e. in some sense deactivating the barometer) ? If not, what other solution could you suggest? Can Garmin developers implement this feature (which I believe should have been there by default*)?
Thank you.
* I have a 2005 model Casio with solar battery, it still works after 17 years (battery never finished) and with its barometer gives as accurate data as Garmin Instinct Solar (because the latter relies on barometer instead of its GPS, this does not sound correct...)
