for take-off they say:
rpm in between 2270 and 3000 with max boost 12 boost either up to 1000 ft for extended time or up to 3 min.

Exacly +12 lbs up to 1000ft or up to 3 minutes. Merlin XII was initialy adopted for 100 Octan fuel not like Merlin III which required modification. Im sure that in SPitfire MK II was allowed for +12 lbs for emergency for short time from the begning. ( initialy up to 3 minutes later up to 5 minutes).
