Anti-Harassment Tools/SecurePoll Improvements/Test Results/20 6 5000 1301235635

Comments

SecurePoll elects candidates 1 and 2.

OpenSTV elects 1, 2, 3, 4, 15 and 19 (the last two being random).

I think the difference is similar to 20_4_5120_824772467. SecurePoll eliminates several candidates at once if they are tied.

See also a slightly modified version of this election, 20_6_5001_1851698519, which does agree with OpenSTV (more-or-less).
