Problem with that would be the unlucky DAL guy who was, say, 5.00001% on his list- he would go to 10%(because of NWA earlier DOH in the ENTIRE NWA group from 5-10%) and his next senior DAL mate would be at 5.0%. In the top 20% of the combined list (2500 pilots) the DAL guys (with the possible exception of the 210 or so pre-85' hires) would automatically lose aprox. 2.5% to EXACTLY 5.0%.
