03_STAR_PR / 02_Examples — proportional STAR worked examples¶
The proportional STAR (STAR-PR) cases: the same 0–5 score ballot, counted so seats reflect the electorate's proportions rather than handing every seat to the largest bloc. Read the reader-friendly pages (cases/cases_pages/); the .yaml beside each is the tabulatable source, and the always-full audit copy is in cases/cases_tabulated/.
Concept first: STAR-PR — the three methods · the math behind proportional STAR · STV vs STAR-PR. Parent folder: 03_STAR_PR.
Same election, three methods (the 63-ballot trio)¶
The 02a/02b/02c files count the same 5-candidate, 63-ballot election three ways — the cleanest way to see how the reweighting rule changes what's counted (they tend to agree on a clean two-coalition electorate).
- Allocated Score — seat the top scorer, then fully spend a quota of their strongest supporters (Equal Vote's recommended STAR-PR) ·
.yaml - Sequentially Spent Score (SSS) — supporters spend score proportionally toward the quota ·
.yaml - Reweighted Range Voting (RRV) — divide each ballot's weight by a growing divisor ·
.yaml
Proportional vs STV, on one shared electorate¶
- Same 3-seat electorate as the STV demo — the STAR-PR counterpart to the STV file; STV and all three STAR-PR methods land on the same proportional slate ·
.yaml
Academic cross-checks (Lackner & Skowron)¶
- Shadow STAR-PR — Allocated Score, k=4 — Lackner & Skowron's running example ·
.yaml - Shadow STAR-PR — RRV, k=4 (matches PAV) — the same example under RRV, which matches Proportional Approval Voting ·
.yaml - RRV sample — three parties (Purple/Orange/Yellow) — 15 candidates, three party blocs ·

Real BetterVoting election¶
One BetterVoting election (bvhchj), two races — the board seats and a party-alignment poll counted alongside them:
- BV2130 — Presidential Board (Allocated Score, 7 seats) — a real BetterVoting STAR-PR election (
bvhchj), 51 candidates, 102 ballots, cross-checked against the LH engine ·.yaml· results ↗ - BV2130 — party alignment (Plurality) — the same election's second race, a choose-one poll over 8 parties: Democrat leads on 39 of 102 first choices and wins. The choose-one companion to the proportional board race above ·
