I have a FR220.
Footpod Calibration is 100% manual ( not via running with the GPS on).
The calibration factor ( CF) is in the .FIT files that get uploaded but not visible on the screen view of the activity.
I would like to see the CF in the run header on the screen IF it was used in the run at all.
I would like to be able to select a box on a run that i can enter the True distance into. GC would then display a new calibration factor on the screen that i can enter into the watch.
If the 220/620 ends up not being able to correctly determine the running distance over time ( like it does with the accelerometer) we could change the CF before a run that has a very different stride.
We could also be offered the option to change the displayed activity with the new total distance ( true distance).
Garmin may be able to use our activity data to tune the pod accelerometer routine OR add a run style selection in the watch ( 1 sprints, 2 Hills, 3 run , 4 jog).
