When i had previously mentioned Max take-off power for all take-offs , i didnt imply ALL available power, balls to the wall, EGT past the max etc. I meant a thrust level which is used to deliver rated engine performance while not exceeding any parameters AND delivering full engine life ! Dont let the bean counters tell you that 1-2 minutes at high thrust ( within limitations) on a good engine will sacrifice reliability and improve overall safety !!! Comprehensive engine inspections and care, proper care and feeding of the engine, High quality maintenance, NO previous overtemps etc and a GOOD engine to start with leads to longevity much more than minimal usage at near max temps etc.
