Any data on this subject?
I've been focusing in Bf-109E-3 tests.
By landing beside a beach and setting the altimeter to 0, the indicated pressure in all maps is 993 mbar.
Ambient temperature is about 17ºC, but I must confirm with Ju-88 and He-111 instruments.
I've also looking for which are the german standards, named "Normaltag" ("Normal Day"):
I'm not sure about the data they considerred standard, but it looks like 1018mbar and 16ºC.
In this test there's a correction factor developed, but I can't undestarnd what every value really means:

If that correction factor is correct, it would mean that with the current pressure and temperature settings for all maps in CoD, we'll never be able to reach the german values of the performance charts like climbing. Even more if it's considered that, as commented in this post, Bf-109 has an overloading problem:

Overloaded E-3 + not so favorable meteorological contitions = our graphs will look always under the german values.
We need to apply correction factors to really evaluate if CoD E-3's performances are correct or not.
