Altitude and elevation issue

[Clément Lavabre]

Hi !

I have owned the Race since its release.
Everything was fine until the update on December 18.

That was before :

And

Beautiful curves, with altitudes and elevation differences correctly calculated.

I do not use the automatic pause, put it when I am stopped, the watch displays the same altitude and does not accumulate any elevation gain.

Everything goes wrong after update 2.30.38.

I no longer have correct altitude data, the altitude differences are exaggerated, sometimes even double the altitude difference calculated compared to real (real compared with a 9 peak pro and Garmin instinct, as well as the GPX track integrated in DEM.

and

And there is also a permanent “noise” of the signal which sees changes of rises and falls where there should be only rise or fall.

I tried to calibrate the altitude at the start, but as soon as I calibrated it varies directly. Even in world shows the alti is not good and varies constantly.

Is this a software problem? an accelerometer that is dead? the baro sensor?
I tried soft-reset and hard-reset but it didn’t change anything.
I hope this is just a bug, and will be fixed in the next update.

What do you think of that?

@Clément-Lavabre It is obvious in this comparison, on one side the 9 baro and on the other the Race

9 baro

And Race

In movement, the precision of the Race is correct, without being excellent. The 9 baro is very precise.

It’s when it stops that it gets bad. We see the flatness of the curve on the 9 baro while the Race varies constantly.

This is how I end up with a lot more elevation
