Has anyone gotten more accuracy out of the fuel level PID from the second post?

I filled my tank today and the values were off:

Empty (fuel gauge directly on the red empty line):
Torque=1.5
Actual=1.2 (Based on 13.2-11.99 gallons filled)

Full:
Torque=12.5
Actual=13.2 (Based on tank capacity)

Undoing the equation in post #2, the fullness at 12.5 gallons comes to a sensor readout of 94.69697.

Does anyone know the technical output of this sensor, is 0 absolute empty and 100.0 absolute full? Or is 94.69697 the fullest the sensor will ever output.

I thought about trying this equation to see if it will give a more accurate output: ((A/94.69697)*13.2)

Just looking to have an accurate read-out for when my gas light is on and I'm trying to decide if I can commute home before filling up.
