I just starting trying to replay a FIT file from an in real life ride, to test my data fields. Seems to work ok. Except if I slide the fader to a point in the ride/file.... the sensor metrics don't seem to respect that control. I printed out elapsedDistance and elapsedTime for example, and they seem to increment every second from the beginning, ignoring the timeline fader. Is that how this works... you can't actually fast forward?
