Be able to compute PA:HR if power data is available (Heart Rate Drift)
If in your training data power is available, you can only calculate Pw:Hr. It is annoying to alter your training data and delete the power data to calculate Pa:Hr. It would be super nice if you could just select the calculated variant with a dropdown of Pw:Hr and Pa:Hr, for example. This would make Heart Rate Drift much more convenient to calculate.
This hit me after the new updates by Garmin, your watch delivers Power with a Garmin strap, and you cannot really turn that off.
