The way I see it 2 points per game all but guarantees promotion. We are ahead of that so all good, so are Newcastle. But Leeds & Reading are not far off that, 4 points each. If they were to each win their next 4 games they too would be on 2 points per game. Unlikely perhaps but should either of them catch up to 2 points per game then 3rd place could have 90+ points. So at least 12 wins from last 20 will do it for me.
BTW I can't see Reading getting close to 2 ppg so that just leaves Leeds.

A string of no score draws would be seriously tedious to watch, though . . . .
