Double standard view on the subject:

The use of +12 in Spifire II is
a) documented in combat reports as "emergency boost" 8 days after the first operational use

Wishful thinking. It doesn't say +12 lbs boost, it says 'emergency boost', which we all know was +9, as per the manual. Selective and wishful use of evidence...

b) authorized in a later edition of the manual

And as such irrelevant for BoB period. Same site you use as a source claims that the 1-min boost for the DB engine was not cleared until 1942, by when the Emil was withdrawn from service. It also claims a gazillion other BS for LW planes and has achieved an unenviable reputation for bias and manipulation as a result.

c) the cut-out is mentioned in the earliest edition of the manual for emergency use. Without a specific modification to +12 boost the cut-out would enable the pilot to obtain any boost up to +17

So by all means model the boost cutout and enable pilots to obtain +17 lbs boost and blow their engines at free will...

On the other hand there is 1.4/1.45 ata for DB601A which
a) is restricted to take-off in any edition of the manual

In contrast of +12 boost being physically restricted (impossible) on the Spitfire II. Nothing restricts the use of 1.4/1.45ata in the 109/110/111, expect for the 1-min clockword which is already present and modelled.

b) is not mentioned by any pilot report for anything else than take-off

Show me say 10 German pilot reports then which 'does not mention it'. No, you have not seen ANY, you just make up an arguement, neglecting the fact that German pilot reports never seem to mention any boost levels during the whole war, and here's why - unlike the British, they had automated systems since the start of the war, so boost levels were meaningless to their pilots - they did not have to set it separately. Neither they needed to overboost woefully undersized engines to compete and thus it was utterly irrelevant to pilots.

Let me show you a real example of double standard.

RAF fans like yourself wish to have a plane modelled in the sim after a crayon graph they drew up themselves in desperation as there is curiously not a single +12 lbs boost report being made, so they had to make up one and wave it around. Ring a bell?

RAF fans like yourself wish NOT to have a plane modelled in the sim after a doucmented and guaranteed tests just because it shows that their cherished RAF plane with much larger drag and 25% greater wing area is, horriblle say, was slower than the blue plane with more power and less drag at sea level.

Said RAF fans then come to the forums and complain about a German rating that was there, and ask for a RAF boost that wasn't there, and wish to model that boost based on no performance test at all.
