HRM-Pro + Epix gen2 - colmpletely not reliable XC-ski skate power!!!

I made to runs: from the first one it was obviously close to reality (based on RPC while I use power with stryd for running and a lot of powermeters for cycling.

1 run - first part was almost ok for the first 18 minutes (correlation with RPC/HR/pace) but afterwards - total mess (linc to my effort https://connect.garmin.com/modern/activity/8231625635)

2 run - here is my run of today - with the hardest efford at the end - last eight minutes with HR at 180 (my maximum is 186) and RPC - 9 out of 10 (https://connect.garmin.com/modern/activity/8252446374)

What I'm doing wrong? Is there any way to get reliable data close to reality?

One guess - somehow it set 128 as an FTP for ski - just got it from settings in GC - there also set Automatic calculation of FTP, so, it updated it to 128 but its strange - now I heve 206 in Stryd for Running and 214 in GC for biking (yes, so small after trauma)...

Return to 206 - will see later... AFAIK it calcualtes power as Stryd did - with a lot of formulas for elevation/acceleration, gliding etc.

I have had the same with fenix 6x and now with my new fenix 7X. So I think issue is with the belt itself not any settings.

So, do we need to raise a support ticket somehow?

After 8.10 it completely doesn't work, only spikes very occasionally

It's better to disable the function, than fool the data!

Hey, Garmin, how can I disable the power or pls repair it!

When did you last change the battery?
