Mmmmmm ....
And with the 412EP the increased Nr also gives you more T/R authority ... as well as improving the rotor disc area ... the 412 with 'slow' (read old) governors will cause a fair bit of coning which in turn can cause all sorts of RPM and therefore Tq oscillations (which the yaw SAS then tries to cure) ... the result is usually an 'Over Torque' !!
