Example (12 July 2000): http://lists.electorama.com/pipermail/election-methods-electorama.com/2000-July/004107.html > Act I: > > AB 18 > BC 14 > CD 12 > DE 19 > EF 15 > FG 16 > GA 11 > DB 13 > GE 17 > > SD chooses candidate A. > > Act II: > > If "DE 19" is changed to "DE 10" then SD chooses > candidate D.
