Is the 40-point mark a myth?

The 40-point mark - the magic number that is supposedly needed to guarantee Premier League survival. But with such a compelling relegation scrap this year, we have to ask, is it still true?
After joining the club in December, West Brom manager Alan Pardew said he would treat himself to a glass of wine when the Baggies reached the 40-point mark, although he added that safety "may be a lot less this year - 35 or 36 points". (They're currently bottom on 20 points, by the way).
BBC Sport and data analysts Gracenote Sports have examined the history of the relegation fight to find out who you can expect to be in the bottom three come the end of the season.
