Spit/109 sea level speed comparisons in 1.08 beta patch

No matter what you do in a 109, if you chose to remain horizontal, the only way of evading the Spitfire would be flying straight. And flying straight is not sustained turn. See?

I do find this theory that the 109 will be able to turn better than a SPit at higher speeds a little foolish.

a) There are no, repeat no tests, from any side that support this theory.
b) The 109 locked up faster than a spitfire at higher speeds so the spit will have all the advantages getting into the turn by which time the 109 will be in the smelly stuff
c) You quickly lose speed in a turn which will nulify any theoretical advantages
d) The above description of what will happen shows the folly of this theory
e) The 12 boost throws the theory out anyway as it passes the power to weight ratio advantage to the SPitfire
f) Its worth remembering what the German test establishment said about the turning ability of these aircraft:-

Before turning fights with the Bf 109 E type, it must be noted in every case, that
all three foreign planes have significantly smaller turning circles and turning times.
An attack on the opponent as well as disengagement can only be accomplished on the basis of
existing superiority in performance.

Notice it doesn't say:-
a) The SPitfire is better at slow speeds
b) That the 109 can turn inside the Spitfire at high speeds
c) Ensure you keep your speed up against the Spitfire in a turning fight

It says basically DON'T GET INTO A TURNING FIGHT.

Can someone explain how the German test establishment got it so wrong.
After all they only had the real aircraft, real pilots to fly mock combats who obviously were very up to date on the Me109, amongst the finest engineers and designers in the world, people both well versed in the theory and experienced in this field, plus the resources of a test establishment.
I repeat the question, how did they get it so wrong?
