Continued Incorrect Ascent Readings

[Dimitrios Kanellopoulos]

@zvonejan those are not used anymore

[nseslija]

@Dimitrios-Kanellopoulos enlighten me about this please, even if a MC is used?

ups :). yes only in movescount and ambit 3. sorry

[Dimitrios Kanellopoulos]

@nseslija he uses Suunto app

[Dimitrios Kanellopoulos]

@zvonejan also S+Spartans but it’s no longer needed. (Altitude is the best option atm)

[nseslija]

@Dimitrios-Kanellopoulos ok, thanks, I was wondering if this is still around for SA use only…

Watch measure air presure and shows that like altitude. We all know that air preasure changes can came from 2 sides ( altitude, barometric changes). So if you run around stadium, suunto 9 can show you altitude changes, which is ridiculous. On ambit you just set to barometer and all changes are consider as weather changes and that is 100% correct. Am I wrong, Dimitri?

actually, barometric changes (the sensor is a barometer) will be interpreted as altitude or weather changes.

For Ambit (and in the past for Spartans+S in MC) you can set in which way sensor data must be used.
Readings are 100% correct if you set this option correctly
Now on Spartans+S this option is “always” set to automatic and switches based on the other data

Only on stadium with barometer mode. If you set watch to altitude or automatic mode and run trail running, there is no guarantee, that all ascent difference is from altitude (some percentage is definitelly from weather changes). Only for old suunto watches of course

[sartoric]

@zvonejan
Well, yes, if you do trail running in “alti” mode and the weather is rapidly changing too the result could be distorted

[freeheeler]

@Nick-Vlahandreas
try Dimitrios’ suggestion with the buff…
I can write books about wrong readings when the strap is too tight or when the wrist position pushes the watch against the arm e.g. during gym workouts etc

[Dimitrios Kanellopoulos]

@zvonejan no you are absolutely right. Not only for that sport of course. If I recall correct (will check that for you) the track and field mode has that set for you. Of course to have some customization (ability to select) is welcome. I wont argue.

That said, have you used the track and field mode and got asc/desc values ?

[mario_b]

@Nick-Vlahandreas what does the ascent/descent values look like in the watch? when you review the activity? do you see the same?

[Dimitrios Kanellopoulos]

@mario_b I checked it for him yes they are the same.

[mario_b]

@Dimitrios-Kanellopoulos ah ok. i think the .fit file would be nice. another test would be choosing (just for testing) running while mountain biking. if that would not count the small up’s and downs, so it would only be a problem with the calculation under the mountain biking profile/app/sport activity.

[mario_b]

@Dimitrios-Kanellopoulos looking at the jumps i think with the fit file, an fit file explorer (viewer) would show nearly 1200-1300 hm too. because this jumps are not 1 or to meters. more 4-5 meters and very often. adding them together it would result in this high number. i don’t know the track. but if there are many small hills, it would be possible.

[Dimitrios Kanellopoulos]

@mario_b I passed it to a DEM and the user is right. Those ±5-10m dips should not be there. There is something wrong with the device or the way its used .

[zvonejan]

track and field mode and got asc/desc values ?

What is track and field mode?. If you run on stadium and watch is set to barometer ( ambit series). watch will fix altitude and all changes of presure will result as weather changes. But now on s9 for example, probably watch will show some altitude changes ( but we all know, there in no altitude changes on stadium with flat surface :))

[Dimitrios Kanellopoulos]

@zvonejan activities -> running -> track

[Dimitrios Kanellopoulos]

@zvonejan but I though it was a special sport mode… now I undersatnd its a basic for running …
