Voting system
Single transferable vote is applied. (https://en.wikipedia.org/wiki/Single_transferable_vote). Voters are required to rank their preference with “1”, “2”, “3”, etc, or use “N” to indicate rejection of a candidate.
Vote counting starts with every voter’s first choice. The candidate with fewest votes is eliminated and those votes are transferred according to their second choice. This process repeats until only one candidate is left, which is the most popular candidate. The result is presented as the approval rate: final votes for the most popular candidate / all valid votes
After the most popular candidate is determined, the whole counting process is repeated by eliminating this candidate, which will find the approval rate for the second most popular candidate. The process repeats until all proposals are ranked with the approval rate calculated.
