much to complex,
i follow the 3 simple Rules Rules by Erich Hartmann, german top ace 352 shotdowns:
1) if you have no advantage, turn away, coffeebreak
2) if you are badly outnumberd, disengage, coffeebreak
3) only attack from above, keep your speed, keep your altitude
(later on in his book he simply remarks, all younger pilots, died after 4-5 sorties, because they begun a turnfight, mostly outnumberd)
