Chips,
Glad you brought that up - The new startup requies the pilot to switch the governor on from 75% (of course it will not work and the throttle will have to be opened).
My concern is just as you say - Many a/c will overspeed due to the governor continuing to open the throttle until it gets the signal it wants, but the lag in engine RPM response will cause RPM to continue to overspeed (not huge) but this does mean that in the life of the a/c this can happen 3000 times, 2000 x average flights of 40 mins......
