However, it is possible to have 2 different methods of calculation for eliminations and elections. In the extreme, you could allow voters to show stronger preferences, where the voter can equal rank but show slight preferences. A: 1a B: 1b C: 2 D: 3a E: 3b would be converted to A>B>C>D>E for determining who gets elected. However, if someone needs to be eliminated, then it becomes A=B>C>D=E If either A or B is still running, then the it counts as a full vote for A and B. Similarly, if A was elected, and B and C were eliminated, then the remaining voting strength would be applied to D and E, without a divide by 2. (but only for determining eliminations). This still partially maintains later no harm. Lower ranked candidates are ignored, however, the method can still look ahead for slight preferences. ---- Election-Methods mailing list - see http://electorama.com/em for list info
