3. STV does *not* achieve proportional representation at all unless there is no vote splitting and just the right number of candidates run who support each group's interests. I.e. the success of methods like STV to achieve proportional representation rest in the unlikely assumption that just the right proportion of candidates run (or more precisely an equal proportion of candidates run) in proportion to the number of voters in each separate group. This is just simple mathematical fact.
STV satisfies the Droop Proportionality Criterion. Any competing proposal for a proportional system must accomplish at least that, it seems to me, to be taken seriously. ----
