Irrelevant when it comes to play offs. Didn't Bristol City beat us twice the year we beat them at Wembley in the play off final? Watford also beat us at their place earlier in the season.
In terms of what happens in the play offs yes - not in terms of our final league position as they are obviously what in the main have got us there!
What gets us there are the points gained and the goals scored less goals conceded but everybody knows that.
