What would be the simplest paper count that will produce a winner in the smith set?<div><br></div><div>I was thinking of just collecting the first preference totals for all candidates, and comparing the top two candidates on a two candidate preferred basis (by examining other ballots). Transfers the votes of the loser to their next preferred candidates, and then do a two candidate count between the last winner and the third candidate. Then, the winner of this contest has a two candidate preferred count against the fourth candidate, and this continues til a candidate has collected a majority of the remaining vote.</div>
<div><br></div><div>This candidate remaining with a majority is our notional winner. Eliminate permanently all candidates which were beaten by this candidate directly, and with the remaining candidates, do a two candidate preferred vote against this notional winner in order of their first preference vote. If they beat this notional winner, they are the winner, however if no-one beats this notional winner, the notional winner becomes the winner.<br>

7 for C (5: C, 2: CB)</div><div>4 for B</div><div>1 for D</div><div>1 for E</div><div><br></div><div>C beats B pairwise 7 to 4.</div><div><br></div><div>C now has a majority of the remaining votes, so it's the notional winner.</div>
<div><br></div><div>Eliminate all candidates C has directly defeated, namely B, D, E.</div><div><br></div><div>Transfer all votes:</div><div><br></div><div>A: 5</div><div>B: 2</div><div><br></div><div>A beats C.</div><div>
<br></div><div>A is the winner. (if the 4: B voters voted 4: BC, then C would have won).</div><div><br></div><div>This method I believe will always pick the member of the smith set with the highest first plurality vote. I don't think it's too much harder to count than IRV, except perhaps in very unusual circumstances. In most cases the notional winner will quickly reach a majority through transfers, and in the few circumstances that this isn't one of the top two candidates, it'll probably be the third. And if it is that just involves a quick pairwise check, of which most of the work has probably already been done, as A and C have already been counted, a number of Bs votes would have already been moved next to A and C's pile, it's only a matter of transferring votes which currently sit with the 4th and lower candidates.</div>
<div><br></div><div>Is there a case where this method won't pick a member of the smith set, or is there a method which still picks a member of the smith set but is easier to do a paper count for?</div><div><br></div><div>
