What exactly is the dog-leg problem? I thougth a dog-leg is used to allow a
smooth progression of string lengths, according to whatever formula one
uses, when the bridge meets a plate strut.

I have also seen pianos designed without doglegs (and not cheap ones) where
the somewhat longer than normal string to the left of the strut didn't seem
to adversely affect the sound.
