I don't believe the Individual Sport Chrono settings are included in the list of items stored on a key. That seems to be limited to ergonomic and comfort settings.
Edit: and now I've gone into the garage, turned the ignition on, found that the Individual settings are still there, turned the ignition off, started the car, cycled through the Sport Chrono modes a couple of times, checked the Individual settings, and found that they are there.
So I've no idea what was going on.
