# Any "bullet vote" - that is, a ballot which votes for only one candidate - is considered a "delegable vote" for a candidate. These votes are tallied for each candidate. Of course, any ballots which vote for "do not delegate" or any other invalid write-in are not considered as bullet votes. |

# If any candidate has an absolute majority at this point, or cannot possibly be beaten by any other candidate using the delegable votes and candidate rankings available, then they win immediately. |

# There is a brief period - perhaps a week or two - for candidates to analyse and negotiate based on these preliminary results. (Actually, in the broad majority of cases, the correct strategies for all candidates and the resulting winner will already be obvious. Usually, all candidates except this winner would concede as soon as preliminary results are announced. However, for the occasional candidate inclined to act irrationally in a way that matters - say, by not delegating to an ally, even though the alternative is to see an enemy elected - this interim period would give them a chance to rethink things and come into reason.) |

# All candidates simultaneously delegate their votes; that is, they choose an N, and add their "delegable vote" total to the approval totals of their top N favorites as announced in step one. They may choose N=0 - that is, not delegate their vote to anyone. They may not choose N=(number of candidates) - that is, delegate their votes to everyone. If they declared a tie in their preferences, they must either delegate to all candidates whom they included in that tie (as well as anyone they ranked above that), or none of them. |

(Note: it would be possible, if there were multiple candidates with an absolute majority at this point, to choose the one of them with the highest initial total. That would be equivalent to considering the delegated votes as middle-rated votes in [[Majority Judgment]]. However, this extra complication would matter so rarely that it is not worth it.) |
