AeroPod, PowerPod and Newton

.
Four profiles for four different bikes in my powerpod.
If I just do the repairing will it overwrite the correct profile or will it over write the last profile I used?
Or do I just use Issac to set the profile before the calibration ride as I would have done previously.

Calibrating on a track is easy. Ride "out". At the 50% mark, stop momentarily. Then, continue riding in the same direction until the ride is complete. Because you're on a track, it already is its own "out and back" route! That's great, I had assumed you had to turn around or it ...

Unless someone knows a workaround the new limitations on calibration, only using an out and back ride, make creating a calibration for use on a track bike impossible.
