Hi. I'm not sure which forum category to put this in. I've been using an Edge 840 since Friday to record cycling activity. I use the Epix gen2 to measure my heart rate and the "transmit heart rate" function, which sends this to the Edge. Unfortunately, I've noticed a significant pattern of stress in the app, and from what I can see, the stress overlaps with the activity (the activity recorded by the Edge). As far as I know, activity should "zero out" the stress level.
