That's also true for my CFC-Kemeny method, which would deal with ranking 
without having to translate the rankings into ratings, but doing a 
CFC-Kemeny election is impractical at the least.

For that matter, every type of combinatorial optimization PR method 
produces a score associated with its assignment. That is, a method that 
tries every council and then picks the one with least (or greatest) 
score. If the calculation does not make use of the number-of-seats 
parameter, it *should* be commensurable across numbers of seats unless 
the scores become subject to some sort of indirect "inflation" due to 
the additional number of seats in the assignments it considers.
