My paid rate does not match the number of minutes I have parked and the hourly rate of the municipality, how is this possible?

Each municipality determines per zone in which time units the parking fee is calculated. In one zone you may therefore pay per minute while in the other zone you pay per quarter. Because the rates shown are calculated on the basis of information from the database, they correspond to the rate you would pay at a parking column on the street. Because the rates are shown per hour in the app, it may be true that this does not exactly correspond to the rate you actually pay for a certain period.
