Ad.1
"Note how it says "Steig- und Kampfleistung"? That clearly shows that these tests were NOT performed at WEP which is referred to in German as "Start- und Notleistung"! So 650km/h at non-Wep can easily be 666km/h at WEP...

And there is a "Steig/Kampf" and "Start/Not" rating for both 1.3ata and 1.42ata meaning that "Start/Not" at 1.3ata does not relate to 1.42ata effectively. "

You know that until med 1943 Db605A was derated to 1.3 Ata - which mean "Steig- und Kampfleistung"

So 1.42 Ata ("Start- und Notleistung") was not allowed until mid 1943.

So real performance of G-2 in 1942 and Bf 109 G-6 early ( 1943) was 1.3 Ata only - as its is in trials which i present.

As I said there is a "Steig/Kampf" and "Start/Not" Rating for both 1.3 and 1.42ata, think of it as 100% and 110% ingame.

As far as these notes lead the test was flown at 1.3ata and "Steig/Kampf" Leistung

1.3ata "Start/Not" is NOT 1.42ata!

Ad.2

Look the same charts. There is 109 G-5 with Db605A clered only for 1.3 Ata
These plane reach :
0 km - 495 km/h
6.5km - 625 km/h

My fault, didnt see the MW-50 mentioned as I only saw DB605A up there and expected a DB605AM for MW-50 use.

Either way, the 495km/h and 625km/h is again ONLY for "Steig/Kampf" Leistung, not for "Start/Not" which is not given in that particular test for whatever reason.
