The process repeats with a normalization step that ignores disqualified choices. A voter's voting power is thus redistributed among the remaining choices. |

If it were not for the "runoff," then generally the best strategy in IRNR[p] is simply to (strategically) plurality-vote, i.e. giving all candidates except one a rating of zero. This is true whenever there are two "frontrunner" candidates judged to be far more likely to win than the others and p is finite (then vote for the best among these two), and its truth is unaffected by the runoff by induction on rounds. |

If p is infinite, IRNR without the runoff would just become equivalent to [[range voting]] in the range [-1, 1] with an extra rule demanding that the best- or worst-rated candidate must have a rating with absolute value 1. The best strategy is then the same as for [[approval voting]] and again this statement's validity is unaffected by adding the runoff. |
