HR tracking bug in the treadmill mode

[FFBPhoto]

I've noticed a problem with the Treadmill monitoring. It's not tracking heart rate properly in the Treadmill mode.

When my heart rate is around 140, the V2 is showing anywhere from 68 to 125.

With Treadmill not activated, it measures heart rate just fine, showing and recording it accurately.

I've done the comparison several times now - 30 minutes with Treadmill on, and 30 without.

In the track below, approximately 16:30 to 17:00 was with Treadmill on. The treadmill itself showed my heart rate was between 125 and 145 most of the time.

17:00 to 17:30 was with Treadmill tracking turned off. It automatically recorded this time frame as a walk in the app.

BTW - the app showing the detailed hr is called Cardiogram (android).
