While you can plan on years of reserve as a DEC, currently at DFW, DECs 11-12 months on property are holding lines (14-15 days off). Granted, all 4 day trips and through the weekends. You could hold a composite line 9-ish months on property. Many of the senior folk bid reserve to stay home and cherry pick trips when they feel like getting out of the house.
So there is hope. But keep in mind this could all change a year from now. YMMV.
