@Lawrence Andrew Leach's link to the SE meta was really useful. So useful, in fact, that I posted an answer to it here, explaining why "optional proportional preferential" voting is the fairest system of all.
@Tonepoet The remaining quarter was what got the candidate elected. The 3x25% is the excess that has to be redistributed.
@WBT It didn't occur to me to downvote anyone. On the other hand, the primary only eliminated one of the 11, so downvoting would have made no difference other than affecting the appearance of personal popularity of a given candidate.
@WBT I haven't changed the icon attached to my username recently. I don't recall changing it at all, except perhaps around the time I joined. Why do you ask?
These elections are so much more straightforward than political elections. In Australia's recent federal election there were 151 candidates for 12 NSW senators!
@curiousdannii What a great video explanation! EL&U and the jungle kingdom seem to have worked it out; now, if only national governments would adopt STV!
Umm, I think maybe New Zealand uses an STV-style system?
