I get your point. An aerobatic aircraft going vertically down will not exceed the propeller RPM, so I based my judgement that a CSU will controll RPM under duress on that experience. I think your point is that transient fluctuations in engine RPM might cause the CSU to "overshoot".
My response is it might have been nice to have seen a paragraph discussing this point in the report. A discussion that this was considered in the report would eliminate our (my) speculation. Its a lightweight report that should not have taken 131 weeks.
