@Stavrogin Well… After two weeks and trying to test things as methodically as possible, my conclusions are the same: when I fall asleep with the watch face upside down, the sleep reading is accurate with respect to the time I fall asleep. Regarding the time I wake up, it’s more variable, although generally quite accurate, in my case. Last night, with the watch updated to version 2.40.38, I tried wearing it on my usual arm, the one that doesn’t leave the watch face down when I fall asleep. Last night, I was especially tired. So much so that I was falling asleep on the couch. I went to bed at 11 PM and I’m pretty sure I fell asleep in 5 minutes. And I got up at 7:30 AM with the alarm. However, in the morning, the log said I fell asleep at 2:46 AM and woke up at 6:48 AM. Sigh… I totally agree with you. It’s frustrating to think that something that wasn’t working before is finally going to work, and it’s still the same… Personally, I’m more disappointed with the swimming measurement, but the feeling is the same. Anyway, it’s only been one night with the new FW, so I’ll keep trying things out. Personally, I don’t care much about what the watch says; I’m not a good sleeper, and this “research” is serving me as motivation to be more aware of what time I go to bed and whether I’m already later than I should be.

@2b2bff Yes, I noticed this today as well, it works as expected now.

and an update: the issue was the watch itself. Got a new one, which works flawlessly. It was not a settings or software issue probably, but hardware

Chase the summit made an interesting comparison on VO2 Max between a lab test and different watch brands. In this video he uses the Race S. I kinda like the results https://youtu.be/i3O1cpQqFhw?si=sgYLZAmd1N595lDx

@jakexuan Thank you for your insight! It certainly is frustrating and does seem like it can be an easy fix… I do rely on the automatic interval count/timing and don’t mind the slight inaccuracy for the easy stuff, but when I am doing any type of speed work, I do need to have full control on the start and finish to have a fully accurate split times As silly as it sounds, I think my only option for when doing main sets would be to switch to a running profile and use the lap duration counter on there

@Luis-de-Paz Training metrics including TSS, TSB, CTL will sync but the individual workouts will not sync back to the watch. So, what you want is not possible.

@BRogers80 I proposed something similar some time ago here https://forum.suunto.com/post/153074

@Brad_Olwin I finally could download them. It just took ages. And they were just regional maps (in France).

@최도원 I have identified the cause of the issue. The “race s” device resets the step count every midnight. The issue seems to occur when the power is turned off before midnight and turned back on in the morning. When the device is powered on in the morning, the time is reset, and as a result, today’s step count is not processed correctly. I have confirmed that this issue does not occur if the device is turned off after midnight and turned back on in the morning. This issue appears to require a fix.
