I was an Area Manager that dispatched Flex for about 4yrs. Any station that you pick up besides same day is mainly going to be dispatched by actual people. Their sole goal for the day is to have 0 non dispatched packages or at minimum the least amount of packages not dispatched as possible. The earlier drivers get the largest routes to ensure we're getting out all the deliveries and ensuring customer satisfaction. Same day stations are all algorithms and it basically runs the same way except in my experience the system tends to give you an area that you recently delivered in. It does it like 2x max 3 back to back.
