What are you saying!  The duplex lengths are obviously intended to 
be, and are in fact, in a simple numerical relationship with the 
speaking length in order to produce a partial of the fundamental. 
That's why they're called "tuned partials".  The staggering is when 
they switch from one partial to another.
