I look at it this way (barring any extreme results):
4 wins for us will be enough .
3 wins are enough to finish above Peterborough.
If Peterborough lose one then 2 wins will be enough to finish above them.
If Huddersfield lose one, then 3 wins will be enough.
If Peterborough lose 1 and Huddersfield lose 2 then 2 wins will be enough.
So out of our remaining 5 games, 2 home wins and 3 away points might well be enough. One extra away point might be necessary if Huddersfield win 3 and draw 1.
