Rounds table

edit

The following table describes the calculations that happened in order to achieve the result above. In each round of calculation, the candidate(s) who achieved more votes than the quota are declared elected. Their surplus votes above the quota are redistributed to the remaining candidates. If nobody achieves the quota, the lowest ranking candidate is eliminated and their votes are redistributed to the remaining candidates. To understand this better, please refer to this link.
