The steps of the methods include: determining a plurality of marketing program segments, wherein each segment corresponds to a unique combination of marketing programs; uniquely correlating each combination of a saleable and distribution channel to a corresponding segment; determining the quantity of at least one measurable for each saleable; and calculating an efficiency value for at least one segment. The systems include a segmentor operatively coupled to a data storage and configured to determine a plurality of marketing program segments, wherein each segment corresponds to a unique combination of marketing programs.

Abstract: An apparatus for reducing buffeting in a vehicle caused by airflow over a removable or retractable roof-opening includes a rail that is mounted adjacently to the leading edge of the roof-opening. Attached to the rail is an angled deflector that diverts the airflow away from the roof-opening. Extending from the top edge of the deflector is a trip segment that causes the airflow to stabilize and reattach at a point beyond the roof-opening of the vehicle.
