Name: Aerobic Decoupling Simple
Author: Phil_Whitehurst

See your aerobic decoupling in real time during an activity.

After a 10 minute warm up, the data field will spend the next 20 minutes calculating your baseline efficiency factor.   It will then update your efficiency factor using an exponentially weighted moving 20 minute average and compare that to your baseline, from this it will derive your aerobic decoupling and show it in real time. Your maximum aerobic decoupling will be shown under the activity stats tab in Garmin Connect.  Best used to track decoupling during a steady cycle or run, though the data field places no such restriction on how you use it.  Note that the value may differ from what other software determines as this uses a rolling average in real time rather than a first half / second half comparison.

For cycling you must have a power meter.  Uses power / heart rate for cycling and speed / heart rate for running.
