Scenario¶

One of four races in the BV2133 "Pet poll II" (BetterVoting election dyxrbr) — 32 voters, four pets (Dog, Cat, Fish, Bird), tallied four ways, each electing a DIFFERENT pet. This is the STAR race: Cat (84) and Fish (72) lead on score and advance; Cat wins the automatic runoff 22-10, so STAR elects the consensus, Cat. The other races elect Dog (Plurality), Fish (RCV-IRV), and Bird (Approval). BV also elects Cat. Live results: https://bettervoting.com/dyxrbr/results

Dog,Cat,Fish,Bird
9: 0,2,1,4
10: 2,4,5,3
7: 3,2,1,0
6: 5,2,1,0

What the engine says¶

The count, step by step — the rounds and how the winner is reached:

[Divergence from STAR]
  STAR                   = Cat
  Choose-One (Plurality) = Dog   (differs from STAR)
  RCV-IRV                = Fish   (differs from STAR)
  Approval               = Bird   (differs from STAR)
  Note: no ballots had tied scores, so RCV-IRV vs STAR here is a genuine
        method difference, not a tie-breaking artifact.
  Note: Ranked Robin (RCV-RR) agrees with STAR, so RCV-IRV is the lone
        outlier — the classic center-squeeze signature.
