OK, you mean for calculating the remaining TTS (time to surface)? As
I've seen I can define different gases for the different segments!?

BTW, coming back to what is missing: Not to forget the CC part :-)

Just to make sure: There is not (yet) a automated ascend based on a
maximum ascend speed!?

I just played around and got some funny looking profiles (saw tooth is a
good description for some of them :-). But I also managed to get a idea
what is working and that looks promising.
