That graph, or the accompanying input is wrong. Only 10 out of the last 20 have been relegated first season. Palace and Watford both finished 17th. So it is 50% survival.
The whole bottom half of the PL is a lottery. I don't think Saints or Swansea can be complacent about their positions long term either but I hope they continue to inspire other smaller clubs outside the dominant 6 or 7 that it's possible to compete, and not simply play to survive in the PL.
Nooo definitely not, I want my club to play against the best every week. If there were a 'Super League' with no promotion or relegation I'd hate it.
GE's right - it's exactly 50%. And I don't think the diffence between 50% and 57.6% is statistically significant. Basically, if you get promoted, you have a one in two chance of staying up.
