This all comes down to complexity and testing.

The next person will tell me "for me my heart rate is more important than
my tank pressure". The next person will say that they need the tissue
saturation graph because a cave diver they yada yada yada and then the
side mount divers want something else.

It doesn't end. There is no feature that doesn't have someone advocating
for it. Yet the more we add, the more crowded the profile gets, the more
complex the combinatorics become when it comes to testing.

It's easy enough for the people who want partial pressures to build their
own Android APK and use that. I don't think that the app from the Google
Play store should contain this.

I believe the correct answer here is that someone needs to create a
"Subsurface-CCR" Android app that caters to the needs of that audience.

I am looking forward to someone writing a label placement AI that manages
to avoid overlap.
