But why do you cumulate the data?
?
maybe we come to RTFQ problem here
Data are not cumulated but separated
(on your graph not shown, but would be if you read Davey post )
Thay are separated and sent to DEST so people there know what to unload and from where.
Data are cumulated on bottom for first flight ( both pax, cgo and mail etc ) so you can have correct weight and balance calculated...
For second flight you would have SECOND graph, without "offloaded cgo pax etc)
