It is locked in from the morning download. Any subsequent deviations from your dispatch (misloads, OCA's, ODPU"s etc.) are not factored into the solution. So even if it does come up with a reasonably good solution, it can go right out the window once you leave the building and enter the real world.
Plus, if you have late air unload, your solution is jacked. A leave building time is entered and if you leave 20 minutes late, the plan is an immediate failure.
Some of the routes that I cover, running section 1 is an Orion priority, even though section 1 is frequently a cut of resi stops.
Last week's route, section 8 seemed to be a priority. It had me run a group of section 8 stops, drive 2 miles to 2 stops that I passed to get to the resi stops; deliver them, drive past the stops I had done and deliver some more. I was over miles 1 day; for the week, I was 20 miles under.
Some routes, have a 20 minute NDA delivery cushion, others have less than 5 minutes. Hard to tell which is which till you get on route and start delivering. Another route, the NDA is loaded with all the packages, Orion wants me to pick out the NDA, deliver other stops and NDA, then go back and deliver the rest of the bulk.
It is silly how easy it is to beat Orion. UPS should return Orion and ask for their money back.
