Have to say I didn't notice it.
Maybe another 'Frankism' to stop pilots forgetting it later? Its also states
Governor On, increase throttle......... RPM102-104% during the starting engine and run-up.
My worry with it is that a pilot may crank the throttle a little too far open, especially on the first (cold) start of the day and the RPM will run away over 80% and the govenor will engage taking the RPM right up to 104%.
