Comments[edit]

SecurePoll and OpenSTV disagree on elected candidates. This is due to how we deal with ties and arithmetic precision.

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

OpenSTV elects candidates 1, 2, 3, 4, 5, 6, 7, 8 and 9. The exact outcome is somewhat determined by randomness. Until round ~107 OpenSTV reports candidate 9 as having the same number of votes as the other candidates. If candidate 9 is eliminated randomly before then, they will not win the election. If it does not, they will.

Candidate 9 is not elected by SecurePoll because the number of votes they receive in round 3 is too small for it to count (1.6776880E-17 according to bc).
