Fighters' weaving

[Lagarto]

Currently, when two flights of fighters fly together, one goes straight and the other weaves above it. Correct me if I'm wrong but that's not the way fighters flew, unless they escorted bombers. When they headed out on a mission, a patrol, sweep or whatever, they just pressed on together. Otherwise the second flight would have used up much more fuel than the first flight, and sooner or later they would have to split up, wouldn't they?

If I'm right, could DT possibly look into the matter and give us a proper fighter formation?
