balanceWithMedian method
Balance your proposal tallies so that they all hold the same total amount of judgments, by filling the gaps with the majority|median grade. This adds judgments of the median grade, as many as needed (if any) to each proposal in order to balance the tallies.
Implementation
PollTally balanceWithMedian() {
final amountOfProposals = proposals.length;
final missingAmounts = estimateMissingJudgments();
for (var i = 0; i < amountOfProposals; i++) {
final missingAmount = missingAmounts[i];
if (0 == missingAmount) continue;
final proposalTally = proposals[i];
final analysis = Analysis()..run(proposalTally, true);
// final analysis = Analysis.of(proposalTally, true); // <= me like
proposalTally.gradesTallies[analysis.medianGrade] += missingAmount;
}
return this;
}
