Comments
SecurePoll elects candidates 1, 2, 3 and 4.

OpenSTV elects candidates 1, 2, 3, 4, 5, and 6.

Candidate 5 has 1 vote. The minimum (in theory) SecurePoll's quota could be is 1, but the lowest it gets here is 2, so candidate 5 is never elected.

Because candidate 5 never exceeds the quota, their votes are never transferred to candidate 6, so they are eliminated. Moreover, the most votes candidate 6 can receive is less than 1, so they can never reach our quota.

Election setup

 * Candidates: 20
 * Seats: 6
