Pets Governance — Delegates by STV (3 seats): proportional again¶

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

Method: STV (proportional, ranked ballots) · 3 seats · Expected winners: Dog, Bird, Cat

Scenario¶

One of six races in the Pets Governance election (BV2134, bvid kcf8vf; BV-confirmed). Same 22 voters, a 13-voter MAJORITY (Dog, Cat, Fish) and a 9-voter MINORITY (Bird, Rabbit, Hamster), voting ranked ballots. This 3-seat Delegates race uses STV (the report below prints the Droop quota it applies). The majority (13) meets two quotas and the minority (9) meets one, so STV elects Dog, Cat (majority) and Bird (minority) — 2 + 1, proportional. Like STAR-PR (Bird, Dog, Fish) it seats the minority; the two proportional methods differ only on the majority's third pick (Cat vs Fish).

Ballots¶

Each row is one voter's ranking, most-preferred first (N: prefix = N identical ballots).

13:Dog>Cat>Fish>Bird>Rabbit>Hamster
9:Bird>Rabbit>Hamster>Fish>Cat>Dog

What the engine says¶

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

--- STV / Single Transferable Vote (multi-winner — 3 seats) ---
  Pets Governance — Delegates by STV (3 seats): proportional again
 Tabulating 22 ballots (ranked ballots).
 3 seats; quota = 5.50 (exact Droop, votes/(seats+1)) — 25.0% of 22.
 Elected at >= quota, and every surplus is measured from it.
 (Hand-count Droop, floor(22/4)+1 = 6, is a different but equally standard rule.)

--- Smith Set (the generalized Condorcet winner) ---
The smallest group whose every member beats every candidate outside it —
the honest answer to "who is even in contention?".
   Smith set (1 of 6): Dog
   Outside (5):        Cat, Fish, Bird, Rabbit, Hamster
   One member ⇒ Dog is the Condorcet winner, beating every rival head-to-head.
