It doesn't matter if an inspection was mandatory or recommended or even to be contemplated, the fact remains that use of +12lbs boost EVEN FOR A FEW SECONDS, DID require the pilot to make a note in the flight log. It was then up to the engineer to determine if the engine needed overhauled based on the fact that +12 boost INCREASED THE RISK OF DAMAGE. He would not be under orders to do this if there was not some good bloody reason for it.

Not one single person replying to your posts is saying a Merlin will break as soon as 5 minutes at +12lbs boost has passed. We are saying the potential for damage was increased the longer it was used. If you don't want to damage your Merlin then turn off CEM. The rest of us will keep it as close to real as possible.
P/O Dutton chose to ignore the 5 min limit. I doubt he was court martialed or penalized in anyway for doing so and his engine may have been a candidate for inspection (as he combined steep dives with overboost), but I doubt he lost any sleep over that.

There is a poster who is claiming that any use of 12lb/3000rpm will result in grounding till a mandatory inspection is done, and I'm glad to see that you disagree with this.

Again, this is exactly what I've been saying. Keep your gauges in the black and 5min+ at 12lb/3000rpm results in increased but still minimal ("low probability") risk, but it is completely ahistorical to claim that pilots did not use 12lb/3000rpm repeatedly or for more than 5 mins as the situation warranted. We know that in the real battle pilots weighed the risks and then "pulled the plug" and some were willing to keep it pulled for more than 5 mins and the game should allow this even with CEM, because that's the way things were. RAFFC went to 100 octane fuel precisely because it allowed the use of 12lb boost and this gave RAFFC a vital edge in performance when it was needed, and some even state that this was the difference between defeat and victory:

It is an established fact that a difference of only 13 points in octane number made possible the defeat of the Luftwaffe by the R.A.F. in the Fall of 1940. This difference, slight as it seems, is sufficient to give a plane the vital "edge" in altitude, rate of climb and maneuverability that spells the difference between defeat and victory.
Why bother with a game that goes to great lengths to accurately model aircraft performance, but then takes away the winning edge that 100 octane fuel (despite all the sweat and cost that RAFFC went to make sure that they could take advantage of it) provided during the battle?
