Comments[edit]

SecurePoll and OpenSTV disagree on elected candidates. This is due to differences in dealing with ties.

SecurePoll elects candidates 1, 2, 3, 4, 5, 6, 7 and 8.

OpenSTV elects candidates 1, 2, 3, 4, 5, 6, 7, 8 and 14, the last being chosen randomly.

This was designed to see how the tally page displays small numbers. In round 3, candidate 9 displays as having 0 votes, but actually has ~7.9E-9. This is less than 5E-7 so is rounded to 0.

Election setup[edit]

  • Candidates: 20
  • Seats: 9
  • Votes: 5000
