Why would the dash readout be inaccurate? It knows how much fuel has been used roughly if the car is on a level surface, and it knows how far you travel in the measured time. Any inaccuracies in the fuel level due to non-level surfaces would average out in time, it should be pretty accurate. The information on the display is a current average from the last reset while fuelly/manual calculations are based on the last fill-up.
