Or at least, if we computed something for O2, that should be a completely different calculation as it would be independent of ambient pressure. But I have to look at the source code to see what we do there really.

OK, that guess was wrong. Our SAC calculation does not notice it’s a CCR dive. That is of course wrong. Created a PR that makes us refuse to compute a SAC for CCR dives.

It’s in the middle of the night and I could not test this since I don’t have any CCR dive data.
