Cheers for that. So, going for something between average and median, we can look to push on for a couple of seasons, but start worrying about 2021!Excluding the top 6, Everton and Aston Villa, the mean average seems to be 4.3 seasons, the median 3 and the most common 1 (6 times). A few teams (including Blackburn, Coventry and Leeds) have been in the PL on average for 10 seasons each!
