      I’ve just reverted to FW 2.40.44 from 2.43.12.

      Reasons:

      • Sleep tracking is underestimating
      • GPS drifting during OW swimming

      The previous FW was performing better, according to my experience.

      Previously used: Cyclosport HAC4, Polar S710, Ambit 2S, Ambit 3S, SSU, S5P, S9P Ti. Currently using: Race Ti.

        I’ve just gone back to firmware 2.40.44 on my Race S, still getting power drops.

          correct, using Stryd via S+ is a separate Bluetooth connection

          That’s what I noticed. I was just curious if the S+ app would be “sharing” its data to the watch, but it appears it’s all self-contained in its own walled garden.

          I’ve said it before many times, Stryd through S+ app creates more issues than it solves.

          I need to frequent the forums more. Heh.

          • Power from STRYD is displayed only on the S+ screen
          • Power on regular screens comes from watch itself
          • No pace, distance or cadence will come from STRYD.
          • Once S+ is connected, Stryd won’t be available as neither power meter or foot pod
          • It creates fit file with 2 power sources Suunto’s and Stryd’s

          Perfect. Thanks!

          • This breaks Stryd offline merge, Stryd didn’t create this S+ app it was Suunto, so Stryd hasn’t done any additional processing on their side to make offline sync work when workout is made with Stryd s+ app

          Yup. I sent in a support request to Stryd about merging the two runs in PowerCenter and Angus said it’s not possible and advised me to not use the S+ Stryd app.

          Which surprised me, as I thought Stryd did the development. But you mentioned that Suunto did, so it’s even more curious that they didn’t develop the app to use the existing paired connection with the foot pods or share the data out of the S+ app to the watch. Shrug.

          Bottom line, stay away from Stryd S+

          Angus advise the same. Haha.

          Known workaround while Suunto fixes power drops and issues with power averages on manual laps is to go back to firmware 2.40.

          I’ll look into this. I’ve already downgraded to .8 and noticed the power drops remain, so I’m skeptical this is a fix. I suspect that the .12 firmware changed something that downgrading isn’t reverting. I’ll give it a go for tomorrow’s easy run and see how it goes.

          Thanks for the confirmation and reply!

            Suunto FIT pulled from the app vs Stryd FIT pulled from the pod via Stryd powercenter.

            If Suunto is syncing the data to Stryd, then I would expect them to be the same. IE, Stryd shouldn’t be manipulating the data Suunto syncs.

            With that said, I don’t know how the offline sync interacts with the existing data. Does the data on the foot pod(s) overwrite the existing power data Suunto already synced over?

            I wonder if for some reason Race S records its own wrist based wattage instead of Stryd power. However, why just sometimes.

            I don’t think that’s the case if the pod(s) are connected to the watch via Bluetooth. The power data written to the storage on the watch should be coming from the pod(s), not the watch.

                    @sryke I just plotted the power for my runs for M-F, including the Tue/Thu doubles. I’m grabbing the Suunto power data from the FIT file downloaded via the Suunto app. I’m grabbing the Stryd data from the JSON file on my Android phone using adb pull after doing an offline sync. That way, I’m getting the unadulterated Suunto and Stryd power data without any shenanigans in PowerCenter.

                    They all agree except Wednesday and Thursday AM. Wednesday disagrees, because I paired my Stryd pods with the Stryd S+ app, which means the power recorded to the watch was Suunto’s built-in running power, not Stryd’s.

                    Thursday AM disagrees in the 4th interval because I paused my watch at an intersection. As such, Stryd’s power data is shifted to the right of Suunto’s as Stryd ignores pauses. However, you can still see that the data would align.

                    Friday morning before my run, I downgraded the firmware on my Race S to 2.40.44 to test if the display would still drop power. It didn’t thankfully, so I think I’ll stick with this going forward.

                      I just ran with 2.40.44 and didn’t see any power drops on the display. I was getting it with 2.43.8 however. But 2.40.44 worked for me.

                        @atoponce Thank you for sharing these details. Your findings aligned with mine. Raw data is not the problem which is a relief. What was changed in the latest firmware I guess is the way Suunto app and watch interpret the power data. When I use a 3rd party tool to analyse power data from Suunto’s Fit files, the average numbers tallied with Stryd’s and not the Suunto App’s and the watch’s.
