I don't recall any mention of speed as it relates to steering in reverse, in this thread. Steerage in a power boat is most often influenced by prop wash being directed by the rudder that is located behind the prop. In reverse, the rudder is located in front (facing in the direction of motion) of the prop, so gets no influence whatsoever from the prop wash. In order to get any help from the rudder, while in reverse, speed through the water needs to be high enough to allow the rudder to get a good bite into the water flowing past it, more than enough to counteract the walk that the propeller is also creating as a sideways force.
As I have observed on my own boats and many others, trouble comes often to the meek, those unwilling to use enough throttle to develop enough speed to give the rudder that good bite.
Of course having twins eliminates this factor, or allows one to use it to your advantage.
