They disagree about the second, and the reason is the whole difference between the two methods: Bloc lets the voter who already got Ben pick the second seat too, while Proportional STAR considers that voter represented and hands the second seat to the voter who has nobody yet. voting_method: allocated num_winners: 2 ballots: |- Ana,Ben,Cleo 0,0,1 # Voter 1 — likes only Cleo, and only mildly 2,3,0 # Voter 2 — prefers Ben, then Ana expected_winners: [Ben, Cleo] # file: min_pr_c3_b2.yaml ====================================================================== TABULATION RESULTS ====================================================================== === The smallest divergence — Proportional STAR (Allocated Score) === Two voters, three candidates, two seats — the smallest election in which Bloc STAR and Proportional STAR (Allocated Score) fill the council differently.
