Thanks for explaining what's happening under the rimes. I was not aware of such adjustments.
Actually my request to Diving Logs is to have the same behavior trough import/export. My test dive was logged as 103m into Aladin Tec2G and SmartTrack. It still was 103m once imported into Diving Log. One I exported in UDCF format it became 105.5 Exported in UDDF it was 103 but it removed the dive spot names. In xml those small misalignment provoked a bug on our side. On the other hand I understand that Diving Log has so many import/export options that it's difficult being always consistent. The road of the digital diver it's a difficult one :) 2014-07-22 19:16 GMT+02:00 Linus Torvalds <[email protected]>: > On Tue, Jul 22, 2014 at 9:08 AM, Davide DB <[email protected]> wrote: > > Good catch indeed! > > So UDDF has the same problem with depths. > > It may not be a "problem". > > Many (most?) dive computers have the notion of a per-dive maximum > depth totally *separately* from the actual sample depths.
