I don't quite see why ranking based
methods (Range, Approval) would not
follow the same principles/definitions
as rating based methods. The sincere
message of the voter was above that she
only slightly prefers B over A but the
strategic vote indicated that she finds
B to be maximally better than A (or
that in order to make B win she better
vote this way).
