Hi all. As you'll see the play offs have reverted once again.
I heard back from NFL.com.
Points difference in head to head record isn't counted.
If two teams' head to head is tied the next tie break is, when two teams are in the same division, division record.
Apologies for the confusion, it seems I was premature (nae for the first time) in making the alteration.

I now very nearly have sympathy with Neil Doncaster..........only nearly though.
