 Not all dive computers report ceiling values. If the dive computer does report it, it may differ
 from the ceilings calculated by _Subsurface_. This is because of the different algorithms and gradient factors available for calculating ceilings, as well as the dynamic way that a
 dive computer can calculate ceilings during a dive.
