Misjudged queue — the free ride achieves nothing¶

Generated from misjudged_queue_hylland.yaml — do not edit by hand. Regenerate: python STARVote_LH_tabulation_engine/tools_adam/scripts/build_yaml_pages.py.

Method: Allocated Score (proportional STAR) · 2 seats · Expected winners: Amara, Boris

Scenario¶

THE FREE RIDE THAT ACHIEVES NOTHING. The minority tries the move that worked in free_ride_hylland_allocated.yaml — scoring their sure winner 4 instead of 5. It changes the result not at all. They misjudged the queue: at 4 stars they are STILL the highest score group, because the majority only gave Amara 3, so they are still spent first and in full. Free riding only pays if it puts someone else above you in the spend order, and a voter cannot know that without knowing how everyone else scored.

Ballots¶

Row 1 = candidate names; each later row is one voter's 0–5 scores (a N × prefix = N identical ballots).

Count:Amara,Boris,Cleo
12:3,5,0
8:4,0,4

What the engine says¶

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

[Divergence from STAR]
  STAR     = Boris
  Approval = Amara   (differs from STAR)

[Runoff Reversal]
 - Score Round Winner(s) = (Amara)
 - Runoff Round Winner   = (Boris)
  Candidate Amara earned the highest total score, but
  Candidate Boris won the automatic runoff — not a malfunction,
  STAR working as designed: the runoff elects the finalist preferred
  by the majority (of voters with a preference).
