Subsurface Dive Planner: Repetitive plans show "0 min duration" in overview and won't carry over residual nitrogen?

Hey everyone,

I’m trying to plan a series of repetitive, multilevel dives using the Subsurface desktop planner. My main goal is to figure out the optimal surface intervals between multiple dives on the same day by looking at the tissue heatmaps and NDL changes. Currently I', just palying around trying to get used to the tool

However, I've hit a frustrating technical issue with the planner workflow:

  1. The 0-Minute Display: When I create a plan and save it, the dive list overview always displays its duration as 0 minutes, even though the plan itself has a full multilevel profile with waypoints.

  2. No Saturation Carry-Over: Because the saved plan sits in the logbook with a duration of 0, creating a subsequent plan right after it doesn't work. Subsurface completely resets the tissue loading, treats the second plan as a brand-new standalone dive, and ignores all residual nitrogen from the first one.

  3. Conversion: I also can't find a way to easily "convert" a saved plan into a "real" dive entry so Subsurface recognizes the actual bottom time for subsequent calculations.

Am I missing a setting to make Subsurface recognize the planned dive's duration in the main list? How do you guys chain multiple planned profiles together to accurately simulate a multi-dive day?
I guess one way could be to just put all dives in one plan with surface intervals at 0 meter?

Thanks for any insights!

Thank you for your report. All three issues seem to come from a single bug (in fact a single character was missing in the source code). I just submitted a patch to fix it. In a short while, on https://github.com/subsurface/subsurface/pull/4989 you should be able to download a version that contains the fix for testing.

Best
Robert

Oh, 

thank you so much. I tested it and it works. I was sunsure if it was a bug or if I was missing something. Would have opened an issue then.
Thank you for the blazing fast fix.

Benedikt
