Usually I use the NEO 2T smart trainer with the windows application and as a sensor in parallel to my Fenix 7 sapphire solar watch, and start a workout there, too, in case of a problem (like a power outage), so that I don't lose the workout. That's how I noticed that there is an 8% difference on the watch, it shows a slightly lower speed and distance covered compared to the computer client (windows and mac too). I tried to see if it was a configuration problem but couldn't find a solution.
