Having accounted for a fair amount of fuzz in the stats, and excluded a lot of irrelevant factors, I have been forced to conclude that the club started falling off the cliff when we stopped playing "Ashes" by Embrace at home games.
You're wrong, our demise started when they started playing Sweet oxf*rd Caroline before kick off.
Oh, so you suggest it was the addition of Neil Diamond's classic, rather than the removal of Ashes, which had the impact? They happened around the same time, so my data wouldn't account for that.
Realistically we need three clubs to test this. One which plays Ashes, one plays Sweet Caroline, and one plays nothing - and then test their level of performance against their historic records across, say, 4 or 5 seasons, to see what if any impact there is.
