subsurface/core/dive.h
Berthold Stoeger acd385048a Prefer real data over planned 
When a dive has both real dive computers as well as at
least a planned version (which is just another dive
computer with a special name), only use the data from
real dive computers for aggregate values like maxdepth,
dive time, average depth etc in order not to have
imagined data on the dive list, statistics etc.
