The center manager I have thinks for herself. She turns off Orion for those of us that the traced is screwed up. She doesn't care about the numbers per se. No accidents, no injuries, run air first if you have to, don't miss business stops. She doesn't care about the Orion compliance metric, doesn't care about miles, and doesn't have us do the stupid stretching in the PCM.
She says keeping injuries/accidents lower allows her to get more routes in and hire extra drivers. It does seem to work that way until she most likely gets moved after Christmas. Then, it will probably go back to a cluster friend when someone new comes in and wants to change the world.
