Where no seats have been filled or where seats remain to be filled, the remaining seats are allocated on the basis of the highest average.
To this end, the number of votes obtained by each list is divided by the number plus one of the seats already allocated to the list. The various lists are ranked in descending order of the averages obtained. The first unfilled seat is allocated to the list with the highest average score.
The same operation is carried out successively for each unfilled seat up to the last.
