I hate to burst your bubble but Orphan Years are Orphan years and treated that way no matter who you worked for last. Lets say you worked for CF for 29 years and ABF for 10 years then retired. You would be an Orphan size cut for the 29 years and take a different cut from the other 10 years that are assigned for ABF. The odd way they are figuring the cuts it would come out about the same within about a few small percentage points. Your over all cut would be about a 48% total cut.
but it is what it is. If by chance you are not retired yet, you may want to wait until after the cuts are in effect. You may have a better chance of getting a smaller cut.
