definition of proportionality is that you have perfect proportional
representation if every voter has exactly the same amount of representation as
each other. Different non-perfect results can be compared in terms of average
squared distance from full proportionality for each voter. Read the method
description from this post on approval voting <a href="http://permalink.gmane.org/gmane.politics.election-methods/24572" target="_blank"><span style="color: blue; mso-bidi-font-size: 12.0pt;">http://permalink.gmane.org/gmane.politics.election-methods/24572</span></a>
but it can also be adapted to score voting based on voter utilities.<o:p></o:p></span></p><font face="Times New Roman">
