getting too much ascent / descent on flat routes

[MatthiasKlug]

@Dimitrios-Kanellopoulos today i ran an identical training on a (flat) track, there are 3m in ascent. Compared to former firmware unfortunately not better.
However If the effect ist die to fused-alti, could this fused-alti bei improved to be as good as before?
Here ist the data
Running_2026-01-15T17_41_32.fit

The (flat) track:

the altitude, this time just a bit off, but still off:

The altitude stats in numbers:

highest point 150 m, lowest point 143 m, ascent 3 m, now lets me wonder if the change in the initial threshold from 3 m -> 2m and meter by meter measurement afterwards does mess numbers for this case?

@Dimitrios-Kanellopoulos thank you for your information.

@Dimitrios-Kanellopoulos said in getting too much ascent / descent on flat routes:

@GiPFELKiND you barometer had noise and ups and downs. So this is not due to the update fyi. WE analyzed the data.

What can i do now? Where the noise is come from? My Sensor is Clean. Thank you for your informations about this

[Dimitrios Kanellopoulos]

@GiPFELKiND nothing. It could be one off or just some water before. If it persists then pm me.

@MatthiasKlug the fused alti has not been touched. This is expected and it’s ok for 3m. For the time being that is.

@GiPFELKiND I’ve always had this happen (with both SUUNTO and Garmin watches) when I run along the beach on a North Sea island. It varies depending on the wind and weather. The stronger the wind, the greater the altitude. The barometer seems to get a bit confused.

@Dimitrios-Kanellopoulos …
but … but … but - it was better before
(and now i can no longer mock the guys that have ascent on a track…this makes a bit sad)
If this is expected, i will be tolerate this expectaion, but still sadly I konw that suunto can do better.
Anyway thanks for your effort on that end.

(edit: my first thought was that this behaviour is somehow temperature related (the bigger the temperature drop the higher the ascent) i just wanted to mention this, we will see if the outer temps get warmer and closer to the changing room, so there is less temperature drop)

Just returned from first run after few months. I tried 5km track run activity on 200m oval 2nd lane, so 208m but that that’s not important. I got 15m descent even on flat track. Don’t know, if it was better before 2.50.26 FW, but according to charts, it seems temperature correlated. At home, I put the watch on jacket sleeve, so the watch temperature was gradually decreasing outside, but not to ambient temperature, which was about 1°C. And the elevation chart curve seems to copy the temperature chart.

@GiPFELKiND Switch off the Baro Mode.

@Sportsfreund you can not switch off the Baro mode
