Multi-winner methods that use pairwise counting, such as [[CPO-STV]] and [[Schulze STV]], instead of doing pairwise matchups between individual candidates, do pairwise matchups between sets of candidates (called [[winner set]]<nowiki/>s).
 
The nature of pairwise preferences prevents direct comparisons of candidates from two separate elections, unlike with [[rated method]]<nowiki/>s. For example, it is possible to compare Reagan's [[approval rating]] to Obama's without having to ask voters about both in the same election/poll, but their pairwise matchup against each other can't be evaluated like that.
