In the early days of the Tornado F3 v F15 (Z list radar), 2v2 usually ended up as 1 F3 dead and 1 running away. You might get an F15 one time in four. Once it got up to 4v4, then it was almost break even, assuming you made the best of the 2 brains in each F3 cockpit by trying to confuse the F15s' air picture.
5v4 worked quite well, if the F15s were expecting 4v4
I do remember being told for the second day running by the F15s that "That cheap trick won't work again" and our QWIL replying "Nope, but we've got 4 more, and there are only 3 days left!"
One did not, of course, ever turn more than 90 degrees for a shot, and then only if the F15 was not reacting. A lot of time was spent running one way or the other at about M1.3
Night was a different story altogether...LJ's your expert there...
Courtney has of course flown both...Thoughts?
