Anti-Harassment Tools/SecurePoll Improvements/Test Results/7 5 1000

Comments
I think this case has been discussed by the team.

SecurePoll elects candidates A, B, C and G.

OpenSTV elects candidates A, B, D, F and G.

SecurePoll differs from OpenSTV because of how we deal with eliminating tied voters.

Election setup
