I like that method. As far as I remember correctly, I have proposed a
similar method on 10 Okt 1997. If you meant that method, when you talked
about the "Dodgson method", then I have to agree with your opinion.
Is it possible, that Condorcet=Dodgson in the UK?
Originally, the Dodgson method looks as follows:
1) Eliminate all those candidates, who are not in the Smith set.
2) Declare that candidate elected, who needs fewest
changes in adjacent preferences to become a Condorcet winner.
