Condorcet methods require the resolution of cycles. Typically, this is done by ignoring "weak" pairwise defeats in favor of "strong" ones. The metric used to distinguish these is called defeat strength.
Measures of defeat strength for a pairwise winner W over a pairwise loser L include:
- winning votes: Defeat strength = votes for W>L
- margins: Defeat strength = (votes for W>L) - (votes for L>W)
- relative margins: Defeat strength = margin ÷ (votes for W≠L)
