election_title: "Crowded field, rung 7 — 7 candidates, 65 voters, counted by Ranked Robin"

scenario_description: |-
  RUNG 3, counted by Ranked Robin — the control for the whole ladder.

  Diego beats all SIX rivals head-to-head. The electorate's answer has not budged since
  rung 1, and Ranked Robin returns it, because a ranked ballot at seven candidates can
  still say which of Clara and Diego a voter prefers: **Diego beats Clara 36–29** right
  here in the round-robin. The 0–5 score ballot in crowded_field_c7_star.yaml largely
  cannot — 25 of 65 voters score the two identically there, and Clara takes the runoff
  23–17 out of what is left.

  So this file is the control, and it carries the caveat that goes with being one: it
  reads a full-resolution ranking while the STAR file reads six rungs. Part of the gap
  between the two at this rung is ballot expressiveness rather than tabulation rule. A
  real 0–5 STAR election really does have only six rungs, so the cost still lands on
  STAR — but it is not the automatic runoff that caused it. The folder README works
  through both halves of that.

  Same 65 voters and the same fixed candidate positions as crowded_field_c7_star.yaml;
  this file hands them a ranked ballot instead of a 0–5 one.

  Construction: build_ladder.py in this folder. 65 voters in seven blocs at 0, 4, 8, 12,
  16, 20, 24 (sizes 6, 10, 13, 9, 12, 8, 7); candidates fixed at Ana 1 · Bruno 6 ·
  Clara 9 · Diego 11 · Elsa 14 · Felix 16 · Greta 22; utility = minus distance; scores =
  each bloc's own min-max scaling onto 0–5. Nothing is tuned, and no count at any rung is
  settled by a tie-break.
