Cume persons growth depends on the dates assigned to the weeks for a station. You may notice a difference in cume in a multi-week schedule if flights have weeks with dates that overlap or don't overlap. The station cume growth is based on the total number of weeks selected that contain spots.
In the simple examples that follow, you can see cume growth changes depending on whether the start dates overlap. As you would expect, cume growth can change when you view the separate weeks in a multi-week flight.
For market schedules with multiple stations, the total weeks is equal to the greatest number of weeks in any one station included in the schedule.
In this example both stations start on the same date which means that Week 1 for both stations overlap. There are two unique weeks in this example.
Each week for these two stations has a different start date, so there is no overlap of weeks. There are three unique weeks in this example. Compare the grand total schedule cume persons in the blue line with the blue line grand total schedule cume persons in the previous example for overlapping weeks.
