Point I'm trying to make is that a series resistor has much more effect at the
top end of the gauge than at the center. Adding enough resistance to
significantly affect the center reading will have a much more dramatic effect at
full scale. (IOW it's very non-linear)
There's certainly nothing wrong with trying a series resistor, but be sure to
check your results at full scale.
