We had one longer dive and in the end we got to the surface, did a short >5 minute briefing and did another 5-minute dive at ~4 meters with surfacing once for 2 or so minutes.
My dive computer (D6) splits dives if you're at least 5 minutes on the surface, so I merged the two dives. You can see what MacDive made out of the profile and I also did a very rough sketch of about what it should look like. (The first surface interval should be longer actually)

What could have gone wrong here? :-S
If needed, I could also send my MacDive database and probably also one with only the two dives I merged in them (would have to create a new database and just import the last ones)
Cheers.
