For what it's worth (if my figures are correct, and they may not be), looking at the leaders after 12 matches in the previous seven seasons, and where they ended up at the end of the season:
2008/09: Birmingham (2nd - automatic)
2009/10: West Brom (2nd - automatic)
2010/11: QPR (Champions)
20011/12: Southampton (2nd - automatic)
2012/13: Leicester (6th - playoffs, not promoted)
2013/14: Burnley (2nd - automatic)
2014/15: Watford (2nd - automatic)
On that basis, having got this far in the first quarter of the season, it looks as if we might have a reasonable shot at second by the end.
