You must have eagles eyes, it took some time for me to spot the difference ;-)
While your first point is correct implementation, your second point appears to
me as a bug, too.
The function on fg_main.cxx takes a PropertyNode with the respective child to
set the sea-level-dewpoint. The child is named "dewpoint-degc" for some
reason. There seems to be no reference to this function, neither in the code
nor in Nasal or GUI dialogs anyway.
But the interpolation shall set the sea-level-dewpoint interpolated from the
source environments, not the altitude dewpoints (which are calculated further
down).
