Its just as well that there is a hard line you cannie fall through with the split,i know the Dees are playing harder games than the bottom six sides however i can't recall the team in 6th being 9th before in the actual points table.
I have seen 7th having more points than 6th fairly often due to the anomalies of the split but its unusual to see the team's currently 8th and 9th also on more points or on a better goal difference.
