Difference in deco ceiling between 4.7.8 and 4.8.3

[John Smith]

Has there been a tweet to the way deco ceilings are calculated recently?

I’ve just updated to 4.8.3 and have the following

I’m running 75/75 and the reported ceiling is 12m.

On my older laptop, I’m still running 4.7.8 and it shows a different ceiling (6m)even though it has the same gradient factors.

There shouldn’t be a difference. Are you sure all the other data is the same (previous dives, gases used)? The calculated heat map looks very similar which makes this even more surprising. Would you mind sharing the relevant part of your log with me (***@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.

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.

It’s the same data shared off the cloud so it should be identical.

Yes,I’ll dump the file to mail later today.
