it really isn't recommended to fill until you see fuel. It is possible for fuel to get into the EVAP system. If it gets into the charcol canister you will have replace it and that can get expensive. Find a method you feel is consitent and use it every time. I started using wagonman76's method and it has worked fairly well for me. By restricting how much fuel is going through it is a little easier to get more fuel in before the back pressure kick.
