Miika,
TL;DR: Works as designed.
I believe this is fine. It is the outcome of the problem with “negative slope”
that we had a few weeks ago. The point is that gradient factors are not really
well defined during the early descent phase of the dive (as GFlow is defined to
apply at the depth of the first stop but there is not really a first stop when
you just entered the water).
For a longer explanation, see my commit message for
e38a473a4d9119b86e5484a03dbf2cafdb8d145c (and also some posts to the mailing
list I wrote in connection with it)
If you think, we need to explain this to our users, I could try to write
something for the manual (or alternatively: a web page to which the manual
could point). But unlikely this week as it’s super busy at work.
Best
Robert
