The odds of getting rerouted are directly proportional to your proximity to ATL, kind of like its the black hole of reroutes, once you are under its gravitational influence you are basically doomed.

I have been mostly based in LAX on NB aircraft the last 21 years and rarely get rerouted - probably average less than once a year. I think every reroute except one was flying into ATL.
I agree that we need to look at this closely for section 6, I imagine if your a NB Pilot based in ATL it can be very frustrating.
