    @freeheeler thanks. I was wondering if the hand motions were different (I assume they are) and that might have caused some discrepancy? It sounds like the accelerometer data is considered along with the barometer measurements when calculating accent. Others will know more.

      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 🙂

          @freeheeler yes - your analysis seems good.

            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?

                  both calibrated at the begining of the activity?

                        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
