Quotient is the number of votes the party needs per seat (valid votes ÷ seats); the seat goes to its candidate with the most votes. Cutoff is the lowest vote total among those elected (the entry threshold for the council), and it is usually much lower than the quotient. Top non-elected is the highest vote total among those not elected, and it can be higher than the cutoff, because the seat belongs to the party before it belongs to the candidate. Learn about the cutoff and the quotient in the tutorial.
