Also, realize that, while voltage to counts is linear, resistance to counts is not linear. This is due to the input impedance of the analog input changing the ideal resistor divider of the pot.
For most users, this is not a problem but you seem to be doing some precision work if you are asking for 1 count.
Lastly, remember that there is a quantization error involved...
