The N1K2 has high (ish) speed flaps on it. You can start dropping flaps @ 220 kias.
Say you are knife fighting with a spitfire. At the start of the fight, when both planes are + 200kias is when the Niki needs to be thinking "position". Get them flaps out as fast as possible. (I will chop throttle untill I 'hear' that 1st notch of flaps drop, then I go full throttle, WEP on if I am pulling heavy G's)
It is this 170-240 kias window that you use to maneuver behind the oopponent, or at least get yourself well on the way to being there. When the fight get's slow the spit starts getting the advantage, or at least parity (depends on the spit).
If you bled E right, and got them flaps out quick, and didn't totally screw up on the merge, you should now be in "controll" of the fight and the opponent in big trouble.
