Perhaps there is another misunderstanding.
By "most approved" I mean "largest approval score".
Hence, if C is approved (=favourite or also approved) by all voters,
but A is only approved by 55% and B only be 45%,
C is the "most approved compromise" (MAC) of any two drawn ballots.

Another small clarification which is however only important in small 
By "draw 2 ballots" I mean "twice draw a ballot at random, with 
because this usually simplifies the analysis a bit.

Yours, Jobst
