ADG is a protection more than a rig. It helps to prevent unproductive pairings from being built. A 2 for 1 duty rig is the other way to skin the same cat. ADG is better imo due to the fact 2 for 1 isn’t better until 10.5 hrs duty in this case. 2 for 1 also doesn’t help with the last min short garbage turn that needs covering. I believe DL might be leading the pack at 530 or 545 but there are others at 5. DL might even be calendar but it is still an average. What do you have right now? It would be helpful if you had a min calendar day to go with that but I’m not sure if anyone has both?
