Hello, an other question I wonder if you could help me with: For single winner elections we currently use the two round system, which is equivalent to the Contingent vote providing that the voter does not change preferences see http://en.wikipedia.org/wiki/Two-round_system and http://en.wikipedia.org/wiki/Contingent_vote
<http://en.wikipedia.org/wiki/Contingent_vote>According to the table on: http://en.wikipedia.org/wiki/Schulze_method#Comparison_with_other_preferential_single-winner_election_methods , Contingent voting <http://en.wikipedia.org/wiki/Sri_Lankan_contingent_vote> has no advantage over Schulze method (apart from being a few dimensions simpler in terms of vote count and understandability for the common person). Two-round voting (although widely used) is not listed in the table. The questions are: 1) Does the two-round system satisfy any criteria, which Schulze method fails, apart from complexity and understandability and the option to change preferences between election rounds? 2) What criteria does the two-round system satisfy that the Contingent vote does not satisfy and vice versa?
