In that case the exceedances would also be recorded in the EMU.
There is no way however that a pilot, let alone an experienced instructor, could miss a RRPM excursion of more the 3 or 4%. And it is easy to correct (manual throttle override).
The scenario the Robinson Safety Notice relates to is where you are on the ground, with RRPM sitting at 100%, and governor inadvertently OFF. When now pulling collective to lift-off, the correlator will open the throttle (increase RRPM) unchecked by the governor.
