Suunto 9 baro very low elevation gain vs other brands

[Dimitrios Kanellopoulos]

@Oktan yeah I got it pal.

@Dimitrios-Kanellopoulos Sorry - I thought my data was unconcerning and should have been clear. For me - this was within an acceptable range of deviation. I was relieved to be honest. You didn’t have to do all of this. I apologize for frustrating you.

[Dimitrios Kanellopoulos]

@fazel no no. It’s ok. I just wanted to explain that many times we can miss some fault etc.

To be honest if I could I would make you a tester as you did take the time Todo that great run and compare.

Actually at your data the s9 I think did a boo boo at the end as I said which I reported.

[fazel]

@Dimitrios-Kanellopoulos thank you - are you referring to the GPS track at the end?

I would love to be a tester. If that ever becomes a possibility please let me know.

[Dimitrios Kanellopoulos]

@fazel no at the elevation difference if you take a look.

[fazel]

@Dimitrios-Kanellopoulos oh wow. I see it now.

I went backcountry skiing with my friend who has well deserved and honourable inherited my A3PS. Of course the watches were not on the same arm, hence a comparison with the slightest scientific touch isn’t possible. However I would like to mention here that we went in the exactly same ascent track and his A3PS recorded around 100m less total ascent plus had issues with the track on the first few meters.

My takeaway is that S9B is not inaccurate at all.
Plus: it’s crazy good to enjoy sports without having issues like these in mind life is easier when we don’t worry

[Oktan]

@TELE-HO Can it be that his jacket blocked the barometer hole for a small period of time, and yours didnt?

[freeheeler]

@Oktan
no, not on A3PS and also not possible when I check the graph

[stromdiddily]

Interesting one for me today…S9 more than doubled the ascent/descent on my route. Green graph is a lot more jagged than the typical results.

Pouring down rain today but it was constant the whole time.

[fazel]

@stromdiddily so light green is today, dark green is a track from the same route ran in the past? I see this sort of delay with FusedAlti, @Brad_Olwin has as well.

[stromdiddily]

@fazel green is today, yellow-ish is from three months ago on the same 7 mile route. The start looks ok tbh but the green is reporting over 1k feet of climbing and the yellow is correctly showing 500ish feet.

Edit - QS feature request, ability to assign colors to merged tracks

@stromdiddily
the spike-ish graph looks like hydraulics did magic on the sensor… it’s a wild guess, but possible

[fazel]

@TELE-HO hydraulics = water?

[freeheeler]

@fazel
my assumption… pouring rain and the baro holes right next to the wrist… it seals great and the movement could create pressure that causes a down spike. once relieved it shows an up spike.
for our luck the recording is not set to every second as it was possible with Ambits, hence it’s somehow equalling out a bit… or let’s say it would be worse

@TELE-HO Sleeve pump effect?

[stromdiddily]

@Fenr1r That’s how I normally wear it, but you’re probably right

[Fenr1r]

@stromdiddily said in Suunto 9 baro very low elevation gain vs other brands:

That’s how I normally wear it

But you don’t normally get this distorted result in the same conditions?

Unless you’ve changed jacket materials or the rain on that run was unusually chubby, my beautiful theory has probably been slain by ugly fact. I’d like to be at least plausible but some other variable(s) must be at work.

[stromdiddily]

@Fenr1r new shake dry jacket (is quite nice actually lol)

Honestly it’s a one off, so not too concerned about it. I just thought it was interesting as I expected to see a super human type jump but instead saw fairly reasonable up/downs on the graph.

[Fenr1r]

@stromdiddily Hmm.

Maybe less chubby rain, more beady jacket. Anyway, you’re right: add it to the PNW’s supply of post-X-Files/Twin Peaks Things Of Interest.
