Curious. What are you defining "static droop" as? In the big picture, "droop" compensation is a function of the airframe N2 control system. Internally (engine/FCU/GOV) the GOV's sole job is to "reschedule" the FCU to maintain N2 turbine speed. There are several "precursors" which must happen before the GOV detects and reacts to maintain that N2 speed. Since the system is mechanical there is a certain "dwell" period between these "precursors" which adds to the transient time period between the GOV's detection and reaction to the power changes. Plus add a second or two for the GOV reaction signal to make its way to the power output of the engine.
FYI: In a B206, the term "droop" relates more to the positive/negative shift in M/R RPM when power is pulled into a hover from 100% Nr at flat pitch. If the Nr does not recover to 100% in a hover then that "droop" is compensated by airframe rigging adjustments. This adjustment physically changes the throw and range of the GOV arm arc as it moves in relation to the collective. It does not reset anything internally in the GOV.
