Rounding down penalises unranked candidates (they share fewer points than they would if they were ranked), while rounding up rewards them. \hline The permutations grow as the candidate count grows, . We can verify this for the Borda system by constructing a table to illustrate the count. If there is a tie, each candidate is awarded 1 2 point. Unlike the Borda count, Nanson and Baldwin are majoritarian and Condorcet methods because they use the fact that a Condorcet winner always has a higher-than-average Borda score relative to other candidates, and the Condorcet loser a lower than average Borda score.

Applied to the preceding example Borda's counting would lead to the following result, in which each candidate receives 3 more points than under tournament counting. This example bears out the comment of the Marquis de Condorcet, who argued that the Borda count "relies on irrelevant factors to form its judgments" and was consequently "bound to lead to error".[7].
