Hi,
I´m running with a Suunto 5 watch, which has only GPS to measure elevation, hence is inaccurate.
The setting “Accurate elevation” is consequently set to “no”.
Nevertheless the elevation gain data on my Suunto watch (source file) is always 100% matching what i see here on Intervals.icu.
Further to that, my elevation gain data on intervals.icu seems to be trending 15-25% below Strava and Runalyze, which are also using some algorhytm to recalculate it.
So my assumption is that the recalculation here may not be taking place.
Any chance, you could kindly have a look?
Thanks
Veronika
You can add the “Fixed Altitude” chart on Intervals.icu to see an updated altitude plot. I had a look and currently Intervals.icu uses the “total_elevation_gain” field from the FIT file and doesn’t updated that after elevation correction. I will have a look at changing that.
I have fixed this. Intervals.icu will recalculate total_elevation_gain from the fixed altitude stream when the file is first processed. Note that it might not be the same as Strava as I suspect Strava has much more accurate topological map data.
Thanks for doing your best 
shall i give you a summary, say based on 1-2 weeks, how the elevations data is tracking versus intial and strava?
That would be cool. Thx
Hi @david ,
Here´s 1 week of evaluation.
If you ask me, it actually looks scary, how much it most likely overstates elevation gain.
Weeks 1-2 without elevation correction on intervals.icu. Week3 with elevations correction.
Suunto is the raw data, Strava and Runalyze they recalculate.
I´d say you´d rather consistently understate it, hence not apply any correction, than so much overstate it.
Still much appreciate your help & effort here.
Thanks,
Vero

Hi @david again!
Few more weeks data in since you updated the code.
Wk04 is missing as i was sick.
FYI - versus Strava, intervals.icu is populating now 35% higher elevations gain on average of these 3 weeks.
Let me know, if you need any more updates on this.
Many thanks!
Vero
Drat … I have changed your settings to not use elevation correction for runs.
