I am also reliably informed that the recovered Nr will be lower when there is no assistance from the engine - even at idle it is producing power - and so the RoD is likely to be higher.
The main point is the surprise and disbelief and the likelihood that it will happen at the most inconvenient moment rather than at a height and speed where an easy glide down to the valley is set up prior to the throttle chop.
