This specific refined type of forecast requires a final sell-out percentage to be first specified (or assumed) and consequently is not applicable for forecasting a potential sellout or oversold condition. However, it is a reasonable calculation of the potential maximum revenue from partially sold out programs. This forecast type can be used on any subdivision of the broadcast time such as Dayparts, Programs or Time of Day. It is most accurate when the rates within the subdivision (such as the rates within one Program) do not vary substantially.
