So I've noticed recently that my altimeter/baramoter settings are really not working properly.

This is a track workout. It fluctuates between 79 and 85 meters of elevation but the track is naturally pancake flat.
I've noticed on other activities too that sometimes despite starting and stopping at the same place my start and end elevations are different!
I've tried calibrating.
Am I expecting too much accuracy or is there a problem?
