Dear,
I've noticed something strange related to the calculation of average heart rate. In my last training session my Garmin 910XT heart rate averaged 65%. When uploading to Garmin Connect I visualized that is showing me a 76% average heart rate. I thought it could be a difference between the values of the device and the application but both are equal, 63 min and 193 Max.
As seen below in the settings tab training zones calculation is performed correctly:
In the detail of training and displayed on PPM is also correct (146 PPM) equivalent to 65%.
But now by selecting % of maximum application shows an average 76% of which is INCORRECT:
What Could Be the problem?
