ya know, i still wonder why these guys continue to say that Range/Score 
does a better job of electing the CW than does a condorcet-compliant 
method.  the information collected from voters is not the same.  you 
could be ranking

     Ghandi > MotherTeresa > Stalin > Satan

and it would make no more difference than if it was 4 candidates, all 
you really liked nearly equally well.  but for Score it makes a big 
difference in how you score it.

how are these apples and oranges compared?  what assumptions are made in 
translating ranked-ballot data to score-ballot data?

i don't see how you can talk about the relationship from Condorcet to 
Score without making some assumptions.  though there *is* a simple and 
direct inverse relationship.
