You're right that I'm wrong about the saltfish method.
It is not necessary that the ropes burn symmetrically for my (EDIT: and your) 30 second solution. If you light the ends simultaneously, you will burn from each end for the same duration of time because the burns terminate at the same time, when they reach each other. Because one burn will burn a whole rope for 60 seconds, two burns working at the same time will require exactly half the time.
