935 Heart Rate

I live in Canada so during the winter I wear it on my wrist with my jacket under it. Therefore the optical reader is not against my skin. The heart rate seems overly high yet showing a number. How so?

Probably picking up on cadence then. Mine does that all the time in cold weather, even against my skin. Pretty common issue with optical HR technology.
