Unfortunately a wooden stick is a very poor tool to measure the amount of fuel in a tank due to wicking and then quick evaporation.
The clear tube with fuel trapped in it gives an exact measurement as long as you make sure it is all the way to the bottom of the tank and you give it a few seconds for the fuel to equalize with the depth of the fuel.
