Most if not all FADEC equipped helicopters have position sensors in the YAW and COLL channels.
The data from the sensors is input into the "mapped" model in the EEC to adjust fuel flow accordingly very accurately without the need for a "governor reset" correction although that function still exists.
A well sorted unit is impeccable with the downside being that it can lull you into a false sense that as the Nr is so stable the rotor must have a lot of mass and therefore inertia.
The reality may not be as you suspect.
