I agree with Linus here. I have many dives where the air temperature is
significantly higher than even the water surface (sometimes more than
10 C difference). It just makes no sense to have that as the first
"water" temperature. I find dives where the temperature plot is
significantly different in the beginning compared to the end of the dive
just... wrong.
