That is not IMO correct. In the case of the SpitII +9lbs basically became the full throttle setting (i.e. the equiv of 6.25Lbs in the MKI) 12Lbs was still available in two ways by way of the throttle gate for take off operations and by Boost Cut out for combat use.

The RAE standard climb tests are flown at +9Lbs Boost for instance.

Yes it was inevitable that "the worst person on the forum to answer his question" would do so and bend it against the RAF. His argument is of course about 'official clearance' in the manual, which is nonsense in RL combat and what actually happened. Indeed, a different throttle with a gate, 9lbs continuous hence the flight tests @ 9lbs (8., recommended 12lbs through the gate for takeoff power to 1000ft however this could still be used below the FTH (about 17k ft) anytime but for limited periods.
