[EM] Participation Criteria and Bucklin - perhaps they *can* work together after all?

[Chris Benham]

Oops! Yes, thanks Abd.
 
I made an error. The A and B group was supposed to add up to 49, not 51. So it should be:
 25: A>Y>X
24: B>Y>X
17: C>D>X
17: E>F>X
17: G>H>X
 
100 ballots, Bucklin election.
 
The majority threshold is 51 and X wins in the third round. But if we add anywhere between 3 and 100
X>Y ballots then Y wins in the second round.

Some error there. Total votes are 102. Majority is 52 votes.
