Thanks, that's very helpful.

It is. At least, the DataTrak software I used to use on Windows showed
detailed air consumption curves, so the data is retrievable somehow. Unless
there's some way for the host to instruct the dive computer to provide more
data, it must be buried in the download.

I'm really hoping to avoid having to find some way to get a copy of Windows
to run DataTrak.

Hmm. Looking at the Aladin and Memomouse pages there certainly doesn't seem
to be any place for tank pressure. But DataTrak *does* display it.

The data format does include a "level of exertion" value that it says is
derived from the computer based on air consumption. I suppose Datatrak
could be using that somehow to estimate consumption... but as I recall it
shows actual tank pressures, too.

I think I'm going to have to find a copy of Windows and validate my
recollections. If I can find a copy of DataTrak... The "buy a new computer"
option is looking more and more attractive ...
