Wildly incorrect spiky altitude data

@sesam or the way you did wear the watch in this particular occasion.

Ok, we missed this info that watch also recorded 600m ascent (which was not the case, at least for me and the cloud issue).
but, but, but, … who knows with bugs
see what you can find and/or share the activity link if no privacy concerns.

@isazi I was thinking about this… I was wearing the watch the same way as always, over the sleeve of my jacket, using a 3rd party HR band. The only difference was that it was snowing like crazy, my clothing and the watch was covered in snow after a short while.

@sesam bingo! It happened to me under the snow a week or so ago, and something similar to @stromdiddily and @freeheeler I believe not long ago.

@isazi I wonder if there were changes somewhere. I don’t remember this popping up as much last year…

@stromdiddily the release notes of version 2.13.18 says:

Fix some pressure sensor issues

But I actually do not know if it is related or not.

@stromdiddily
weather changes… we haven’t had that much snow in ages!!

It’s a bit of a drawback that we only have one sensor for measuring. Two sensors or at least channels from different sides would really really help here.

I know that Suunto uses Creo to design watches… maybe I should apply as a designer and give them a hand with the future baro watches

@freeheeler well, it’s been raining pretty steady where I’m at since…forever lol

I really liked the location of the sensor on the A3P. I am not a fan of the side sensors for this very reason.

Don’t go so fast, if there is an opening I’ll apply first…Creo is my friend too.

@cosmecosta
maybe they need 2 great design engineers

And then it totally redeems itself. Off by 5 feet at the top of the summit on today’s run.

I think it is better to just feed all data into tensor flow and give it as much as possible correct keys to learn how to deal with these conditions. I had better experience with S9 when biking than with A3P. Under certain conditions with S9B I have 600m ascent instead of 6m but with A3P I had predictable errors due to wind.
