Stryd pace/distance affected by bad GPS on S9PP

[herlas]

Posted a bit about this in the main S9PP thread, however as issue has repeated twice and I’ve opened a separate thread for it.

I have Stryd paired with S9PP as foot pod only and get pace and distance from it, which always has been my go-to approach to avoid issues with pace and distance being off due to bad GPS, whatever the case may be, tall buldings, bad weather, etc.

For the first time (couple of times in fact) bad GPS on watch has affected my pace/distance, in both situations, I’ve looked at the watch and immediately noticed the distance wrongly measured.

After the fact also in SA noticed the spikes in pace/speed during the bad GPS track portion.

I’ve reached out to Stryd support and they looked at the offline file (data recorded by pod itself ) and it was determined that Stryd is not recording such spikes, so they’re pointing to something to do with the Suunto watch.
In their own words “I am pretty sure this is Suunto watch issue. I think the watch was using GPS pace in the beginning. Not sure why.”

For the sake of this report, I’m adding the screenshots from the two occurances, I got the offline data from Stryd and some SA screenshots that show the pace spikes.

Stryd colors: power in yellow, pace in blue
Red arrows point to the wrong GPS track in SA
Red circles indicate the pace spikes (in the case of the SA) and the normal OK pace in the Stryd offline data.

Watch having GPS issues is something we know happens more than we want it to, but the watch using GPS pace/distance when it’s setup to use Stryd’s is the main issue here.

Is this something we can report to Suunto? let me know what you all think, thx for reading
