[EM] Proportional multi-winner ranked voting methods - guidelines?

[Markus Schulze]

Hallo,

it is difficult to compare Schulze STV and Tideman's CPO-STV,
because there are too few established criteria for STV methods.
However, Schulze STV has the property that, when there is some
candidate X who wins in every (S+1)-candidate contest (where
S is the number of seats), then this candidate X is also a
winner overall.
