Cadence reading from Vortex.

I notice somewhat higher cadence reading at higher speeds and power. Haven’t had a chance to confirm the reading as of yet but I know how it feels compared to my road efforts.
Anyone knows how is cadence calculated and is it done by the Vortex smart or the Zwift app?

I believe the cadence reading showing up from the Vortex is actually a bug that just hasn’t been fixed, since we don’t like to show virtual cadence. It’s been around since beta, so I don’t know if it’s going to get removed any time soon, but I wouldn’t use it as a measurement if you have a separate cadence sensor you can use instead.

Thank you Jason.
I had an opportunity to pair the Wahoo cadence sensor with the app and it works great. All readings are right on the money now.
