That's why I said '... backends COULD add support...'

Most every dive computer sold in the last half dozen years obviously
calculates these numbers. So the question becomes "which ones provide it
in the download" and of those "which document it / are easy enough to
reverse engineer for us to figure it out".

Brilliant design...

The more I engage with software interacting with dive computers, the
more I wonder about the wisdom of trusting my health to them :-/
