I'm struggling with some of the logic behind the use of 12lbs here.......for the life of me I can't think of a single circumstance where a pilot would need to break a sealed lever to get an emergency take off boost in a single engine aircraft, take off performance should be accounted for using max available non emergency power...........OR have I got the wrong idea and 12lbs boost was available without breaking the seal but was instead achieved by use of a throttle gate and was automatically reduced above 1000' and if you hadn't climbed above 1000' on departure you were expected to reduce after a max of 3 minutes? thereafter the max boost was 9lbs?........which means that the sealed boost lever has not yet been used.......I wonder what would happen if I used it?
