=== Independence of unranked candidates===
The negative approach doesn't require additional marks to be made for a given ballot when candidates are added to the election that that ballot doesn't vote for. For example, at most 3 marks need be made for a voter whose ballot is A>B, regardless of whether there are 2 candidates in the election or 100.

* Whether there are 2 candidates in this election or 6, negative pairwise counting only requires from 1 to 3 tally marks; but regular pairwise counting can require from 1 to 9 tally marks.
