Method: STAR (single winner) · 1 seat · Expected winner: Strawberry

Scenario

Reference example that sets every supported field and display option, so you can see exactly what each one does. Single-winner STAR over four candidates; the finalists-only matrix, Condorcet line, and score distribution are all on.

Ballots

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

Choco,Almond,Vanilla,Strawberry
     0,     2,     3,         5
     0,     2,     3,         5
     0,     2,     5,         3

What the engine says

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

[Divergence from STAR]
  STAR     = Strawberry
  Approval = Vanilla   (differs from STAR)
