::2.1 '''Voters choose their favorite candidate.''' The ballot lists the candidates running locally. There is also some way to vote for any candidate in another district — perhaps as a write-in, or perhaps using an extended ballot which lists all candidates, or perhaps nearby candidates are listed while far-off ones must be written in. Finally, there is an option to simply vote for a party but not for the local candidate; if write-ins are available, this is done by checking a write-in line for a given party but then leaving it blank. |

::2.2 '''Ballots are tallied''' and each vote is converted to a transfer order. As stated above, a candidate's faction allies have first priority, then members of the same party, then coalition allies. Within each of these groups priority goes from highest to lowest direct vote total. If all these groups run out, a ballot is exhausted. Votes are never transferred to candidates who have been eliminated or who have already accumulated a full average district worth of votes. |
|||
::2.2 Ballots are tallied, and '''any candidate who got less than 25% of the local vote is eliminated''' (unless they got more local votes than any other). |
|||
::2.3 '''Votes are transferred until only one winner remains per district.''' |
|||
::2.3 '''Votes are transferred until a full slate of winners has one equal "quota" of votes each''', with less than one "quota" total of wasted votes. (If this is not possible because all the backup options for some votes are exhausted, the transfer method comes as close as it can.) |

Of the three steps directly above, voters only have to worry about step 2.1. They can leave the details of step 2.3, the transfer process, to the experts. Though those details are a bit more technical, they are basically STV (Single Transferable Voting), a well-known proportional representation method. |

:::2.3.1 A "quota" is defined as the average number of votes per district. |
|||
:::2.3.1 A "quota" is defined as V/(S+1), where V is the total number of votes and S is the number of seats. So in an election for 9 seats, a quota would be 10% of the total votes, or 90% of the average district's votes; and less than one quota of wasted votes would be left over after all winners are chosen. Any candidate with a quota of votes immediately wins (unless some other candidate in the same district with more direct votes also has a quota). |
|||
:::2.3.2 If a |
:::2.3.2 If a candidate ever has more than a full quota of votes, the fraction of each of their votes above that is transferred. For instance, if one candidate got two quotas of votes, then half of each of those votes would be used up and the other half would be transferred as "excess". Thus, transfers can involve partial votes. |
||
:::2.3.3 A candidate X can be eliminated for three reasons: |
|||
:::2.3.3 Until all seats are full, the candidate that is farthest behind the frontrunner in their district is eliminated, one by one. As soon as a candidate is elected, all other candidates in the same district are eliminated. Votes for eliminated candidates are transferred, based on the candidate for whom they were originally cast. As stated above, faction allies have first priority, then members of the same party, then coalition allies. Within each of these groups priority goes from highest to lowest direct vote total. If all these groups run out, a ballot is exhausted. |
|||
::::2.3.3.1 X has less than 25% of the local votes in her (his) own district, or less than half the local votes of the frontrunner in her district. |
|||
::::2.3.3.2 Another candidate in X's district has accumulated an average district's worth of votes. If two or more candidates reach this total simultaneously, whichever originally got fewer local votes is eliminated. |
|||
::::2.3.3.3 The difference between the number of votes currently held by X and the candidate Y who currently holds the most votes in X's district, is greater than the similarly-defined difference for any candidate Z?X. This rule applies whenever there are no more candidates to eliminate for reasons 1 or 2, and will typically apply multiple times before there's one winner per district left. |

Thus votes will move from weaker candidates to stronger ones until they make up full quotas and the seats fill up. |
