Obviously the targets will be different for different routes. If you assume that's 400 packages delivered to 400 separate single family homes then it doesn't work. But if it's 400 packages delivered to 200 apartments/condos served by 20 mailrooms, that's doable. We often get two or three Amazon packages in one delivery. There are easily 20+ packages dropped off all at once in the mailroom of our building most days.
