Decoplanner, old version.

When I try to fill in cylinder size, 7 liters, from the default 3 liter, and then hit "apply", it will not change when I plan a dive. The 3 liter comes up all the time :(

What am I doing wrong?

I have rebooted my computer, and reinstall "Dp", so I'm not a beginner at the program...

Stupid little me... I restarted the program, so now is 7 liter default...:D

Decoplanner (ver 2.0.49) also gets confused, if one tries to
manually input back-gas breaks. For example, if I model a dive
to 58 meters for 40 minutes, using Trimix 18/45 and EAN50 and O2 in
decos, I get 40 minutes at 6 meters (GF 25/80).
If I now try to input to the Depth Plan table this 40 minutes, splitted to
5 minutes Tx18/45, 20 minutes O2, 5 min Tx18/45 and 20 minutes O2,
things get wild.

The plan in 6 meters is (note the given CNS readings also!!) now:

6m 5min Tx18/45 CNS 90% (cumulative, so far)
6m 12min O2 CNS 89
6m 20min O2 CNS 78
6m 1min O2 CNS 78
6m 5min Tx18/45 CNS 78
6m 1min O2 CNS 78
6m 20min O2 CNS 77
6m 26min O2 CNS 77
CNS 92 Total (??)

So, the cumulative CNS reading *decreases* while on oxygen in some points of deco, and the software wants to make some minutes on O2 at 6 m, even that the depth is constantly 6m, and I am already on O2.

I don't do back-gas break plan like this, but this "feature" was something that I realized some time ago, when I played with the software.

Have a nice & safe diving! :)
