When were they disconnected?
A good question - do you have the answer? I also think not. if the rudder broke away then the linkages would be the next to go.
As regards sensitivity, of course the rudder gets more sensitive as Q increases. This was the reason for the rudder limiter on such classics as the MD-80, where from around 17deg+- at circuit speeds, only round 2.5deg+- were available at cruise speed, depending on model.
The pilots had the reason for this explained to them during instruction on type.
The guy who designed that knew why but as with 411's pilots, the new age designers have missed out on some hard earned experience.
