I think the right way to take care of this is to support multiple
profiles per dive. When you use multiple computers on a single dive,
this should also be considered a single dive in your logbook. I mean a
logbook is used to track your dives, not the individual dive profiles.
When I dive with multiple computers, the dive details (date/time,
maxdepth, dive time, tank pressure) is an aggregate of those dive
computers. For example my main dive computer (ostc) supplies most of the
info, except tank pressure (because it's not air integrated). So I take
that from my backup computer (cobalt), or fill it in manually (analog
pressure gauge). For this kind of data, I don't care about the (minor)
differences between the devices, and the aggregated data is all I need.
But for the dive profiles, it would be great to be able to view the
individual profiles from each device.
If this would be possible, the numbering problem would disappear,
because there won't be any duplicates anymore. After importing from
multiple devices, those duplicated dives would be merged (manually or
automatically) into a single dive.
