Note: Version 7 of the Garmin Edge 1000 has a bug that prevents config from getting saved, update to the latest version will solve the problem.

This is a very early proof of concept data field that attempt to reverse calculate a "CdA like" value for cycling by using inputs from preset values as well as real time power meter information. Do note that this is not a true CdA as it does not includes dynamic environment factors such as wind, air pressure change, road surface change. Prediction of those dynamic variable might be implemented in the future, so for now they are a static variable that you need to preconfigure via Garmin Connect or Garmin Express.

Currently the data are not filtered so you will see a wide jump in the results, the correct values that you should be watching for is around 0.2-1 once you start to maintain a constant power and flat environment, the tailing P denotes pedaling and C denotes coasting.

Note and Disclaimer:
*Power meter is required
*Accuracy of the data might varies from useful to total rubbish.

To be configured via Garmin Connect/Garmin Express:
Average (s) - Default 10s, the sample length that you wish to smooth the output
Bike Weight (kg) - Bike weight in kg
rho (kg/m^3) - Air pressure.
Coefficient of rolling resistance - rolling resistance of your wheels
Drivetrain efficiency - The overall efficiency of your entire drivetrain in %
