I'm guessing here that this team put a potentiometer on the pivot of this arm. The movement of the arm turns the shaft of the pot and they are taking a voltage drop across the resistor to translate into angle...the knob and the "11" are only decorative (but great).

That is 100% correct. The POT gives us the position of the arm allowing us to then do presets on the arm, have more precise control in autonomous and plus... it can go to eleven just in case we need to move the arm just that little bit further .
