(Moved points pertaining to MMPO to a subindent of MMPO. Though the statements apply to MMPO, the claim that every pairwise opposition method passes LNH and FBC and fail Plurality should be cited or shown.) |

Line 7:
=== Standard ===
* '''winning votes (wv)''' = number of votes for W>L if greater than the number of votes for L>W, otherwise zero.
* '''margins''' = (number of votes for W>L) - (number of votes for L>W)
** Gives more strategic incentive than wv but may be easier to understand
* '''pairwise (non)opposition''': number of votes for W≥L, or equivalently 1 - votes for L > W
** Strong intuitive appeal (pick the candidate opposed by the least voters)
** Example method: [[MMPO]]
*** Gives even less strategic incentive than wv (satisfies later-no-help and favorite betrayal).
*** Violates [[plurality criterion]]. A complete unknown can win with no real support, just because everyone forgot to rank them on their ballot.
