The key word is "Daily or Pre-flight checks" - I think that may be the walk-around checks, where you open the cowl and press all the test buttons. Doesn't look like a check which is done when you're strapped in doing the pre-start stuff.
As part of a Check-A (UK specific walkaround which must be done if the a/c is to be flown Public Transport) I also check the rotor brake, RPM and governor lights.
I seem to recall that mention when I talked to people after my overspeed that Robinson wanted the governor on below 80% to check the governor function across thw whole range. I tend also to that, as part of the Low RPM horn check, the governor returns RPM from below 97% to normal operating.
