It depends on what stage of delivery they're scanning the packages. I used to ship a lot of small packages for a small business, and noticed:

- they don't get scanned into tracking until they get processed at the facility, which can take a day

- they sometimes get scanned "out" when they're loaded onto the truck, rather than at delivery point.

Since the directive is now to leave on time, rather than wait for all the packages to make it onto the truck, I bet they're getting scanned out and then waiting on the floor for the next day's truck to actually get delivered.

UPS/FedEx etc use handheld scanners at the delivery point, so they have to deal with employees faking delivery and making up for it later.
