At this stage in 2010 we had 55 points and were third, 4 points from West Brom in second. In our last 15 games we scored another 24 points to reach 79 (1.6 per game)
At this stage in 2011 we were actually second with 56 points, ahead of Swansea in third on goal difference. We went on to score just 19 points in the last 15 games to reach 75 (1.26 per game).
In 2014 we were 5th with 55 points, 5 from second and 9 ahead of 7th. Unbelievably, we scored just 10 more points all season.
Interestingly, at this stage last season Sheffield United had 55 points. They scored another 34 in their final 15 games, at 2.26 per game and finished 6 points ahead of Leeds.
We need around 1.5 points per game from now on to more or less be sure of the playoffs.
To reach 90 points we would need 2.6 per game. Very tall order for any side.
But to reach 85 we would need around 2 points per game. That's an improvement on our current 1.74 per game, but not undoable.
