It's pretty interesting to watch the display on Tunelab as I do a pitch raise 
of epic proportions, especially in the killer octave section.  

For those unfamiliar Tunelab(Pocket, in my case), it works like this:  each 
string has it's own spike in the graph.  Get the unison tight, and there is 
only one spike.  When I show customers what happens during a pitch raise, and 
they can SEE the pitch on the neighboring string change with their eyes(many 
couldn't be expected to hear it), they begin to understand the concept of a pitch 
raise a little better.

I don't know if it's the backscale or not, but I'm willing to take the word 
of those with a better grasp of the physics of it.
