I have all recent updates installed and use Zwift in Windows 11 with a Zwift Hub.
Since a few weeks the 3 seconds average of power seems not to work. Power is jumping literally every second and never stands still. I tried to switch on/off the 3 seconds option but its not working. I also use the Zwift cog…if thats important.
Apparently it was fixed in version 1.57 but this update was rolled back in 1.57.3, should be back in the next major update (1.58).
Power values displayed during Workouts are now more stable when using devices that broadcast power readings at 10 Hz with the “3-second power average” setting enabled.
