It has no bearing or relevance. BMW tested the BMW801D2, including flight test of the aircraft, to 2.2 ata but the engine never saw a service rating above 1.65ata.
It is not intellectually honest to make the claim the engine was then capable of 2.2 ata. It was not capable of reliable operation at that boost level and that is reason it did not enter service. Same goes for the Merlin II and III.
If you want to know what an airplane can do, check the latest edition of the Operating Instructions. That is what was approved and in use.
No speculation required!!

The +16PSI on Sea Hurris are irrelevant indeed.
Sir, as stated before, the Spitfire Mk.I was flying at +12PSI Boost. The figure of +16PSI was only mentioned in a reply to TomcatViP regarding the overboosting of early Merlin engines. No one ever said that such a rating should be modelled for Spitfires Mk.I or Hurricanes Mk.I ingame!
We're saying the same thing btw, no need to argue.
