I hadn't realized this is how they worked... very elegant.  So, if I 
want to get to another position quickly, I could exaggerate the position 
to maximize the error to increase the movement per pulse, and then sent 
the correct position to zero in on it.  This would have to take into 
account the characteristics of the servo, but could give better 
performance.
