In the Battle of Britain 1940 Park used his fighters to put up a screen to cover possibilities as an attack developed. The RAF would always have more fuel in their fighters than the LW because the LW had to form up and cross the channel, the LW also had to go back whereas an RAF plane could force land in a field if out of fuel. There were many cases where the RAF were taken by surprise and had to scramble to altitude, in that case you cannot take the additional fuel out and all it does is increase your take off run and decrease your rate of climb.I think you should read and understand what I am saying, more fuel allows more flexibility, flying feints and bogus raids is part of warfare, flexibility gives you options to deal with it instead of guessing your enemy's intensions.
