Difference in deco ceiling between 4.7.8 and 4.8.3

[Jason Bramwell]

There was a bug with this 4.8.2 and 4.8.3 where only one set of gradient factors were used regardless what you had set. That bug has already been fixed.

Whether that particular bug is the same as yours (it sounds like it is) I’m not 100% sure.

Would you mind sharing the relevant part of your log with me (helling at atdotde.de) so I can have a look? In the recent version, in the dive export you can strip out the text data for the export.
