Also depending on the resistance of the track in the pot, which might
not be linear.  It could be that the output of the pot is corrected this
way to be linear with fuel consumed, of course.

There you go.

I hated the computer in my 90Q because it had nothing I wanted to watch
all the time (clock is separate), and doesn't turn "off."  So I got a
