Subsurface sees that and allows one to view the different dive
representations by selecting the _Next DC_ or _Previous DC_ menu options.
However, if I plan a dive with the same date, time and location as a logged
dive, the plan and log are shown as separate entries on the dive list. What
determines whether two representations of the same dive are considered as a
single dive with different dive computers?

That's definitely a good point, but there might be a case where doing this
backwards makes sense.  I suppose you could want to show the planned
profile with the dived profile (as per your suggestion below), and if you
didn't save the plan originally you might try to recreate it when logging
the dive.

Then merge the two dives. You will end with a single dive which has the
plan in the notes and 2 profiles, the real one and the planned one. Then
edit as usual.

Thanks Salva, that's a great suggestion. I've never thought of doing it
this way.

Cheers,
