Is the real need not for the citizen or the electorate to know the calculation that is taking place on how the ballot gets counted but rather what their vote will mean? In the Condorcet model, the weighted model that you spoke of, you effectively tell the elector that each candidate is preferred to all the other candidates in that riding. It's not a preferential ballot. It doesn't increase the seat magnitude in the district, but it does, in that case, deliver a candidate who is preferred to all other candidates by the greatest number of electors.
Is it important no matter what system of balloting you use that we allow the citizen to know what it means as opposed to how it is calculated?
