Milo,
You are so blinded by your absolute fandom. You and Izzy are cut from the same cloth on opposite sides of the coin.
Shame too. You probably have some good things to contribute that your crappy personality just covers up.
Obviously you have no clue what I am refering too in this.
Let me spell it out.
At all times if the FW-190 stays at 250mph it can Leave the Spitfire behind in the climb.
The angle and speed vary with altitude, the closer the gap the higher an angle and lower speed the FW can climb. For some altitudes the FW-190 can simply just outclimb the Spitfire at its best speed/angle.
