    it could be possible that I’ve had a similar “setup” like @stromdiddily had recently during his run. Lot of wet stuff and the sensor holes just on top of the jackets cuff.
    When zooming in the graph I can see tiny spikes… maybe I should entertain myself tonight and count all the irregular deltas 😉
    The last couple of ski tours gave a more reasonable result. I’m not sure if it’s this. But what I actually wanted to point out is that I have the impression that S9B is not calculating way to low.

      this graph is from a hike with poles. Hence similar movement like ski touring. When I zoom in the graph is impressively less noisy. It was a dry and sunny day. I assume that raindrops and hence molten snowflakes in combo with a garment can influence the recording.
      I did not check the total ascent as this activity has more ups and downs plus a bike ride at the beginning and the end (and a pause for getting wet shirt changed). But just the fact that the graph has less noise is interesting, at least for me 🙂

          Today I experienced something similar to @freeheeler. I went running outside and it was snowing (first snow in a long while in Amsterdam!), and got 47/49 (ascent/descent) on a route where I usually get ~10 meters. Corrected elevation seems something like 12/13 (I did play a little bit with Runalyze).

          The common pattern seems to be rain/snow. First time this happen to me.

          Also, when I got home the altitude on the watch kept changing rapidly (-3 when I stopped the exercise, 0 when I arrived home, then -2 a minute later, +2 next time I checked, and so on).

          Currently the watch is taking a warm bath to calm down 🙂

              Hi again,
              Sorry, but I’m still annoyed by this issue.
              Both S9B and A3P on handle bar, recorded exactly the same ride: S9B recorded 539m elevation gain and A3P recorded 641m.
              How could it be?

                      I would bet on wind effect on S9B and lateral holes.

                      If confirmed by Dimitrios, try protecting holes with something like this 😂

                        @mff73 nah then the s9 would have had more. I suspect the opposite

                                    @oktan the reason is because ambit 3 looks more jaggy in the data.

                                      @dimitrios-kanellopoulos Ambit3 barometer has 1 meter resolution, Suunto 9 - 20 cm resolution if I remember correctly from looking at the FIT files - either that or Suunto 9 averages over 5 seconds which makes the altitude resolution look more fine grained. But that isn’t the reason Ambit3 has more elevation gain and Suunto 9 has less. These graphs don’t reflect elevation gain because if you simply add all changes on the graphs, that not what the watches report.

                                        @sky-runner yeah but adding all the changes even on QS that does not use those filters A3 has way more

                                          I agree, I’ve been fighting since I bought it with support, from 2020. I joined this forum just to see if I’m the only one and if there is a solution. I have the 9 baro, I use it on a dinghy sail boat, they are always at unsuitable heights or -25m or +30. I’m thinking of selling it.
