Actually there might be something in that.
Should a team that is in the premier league for just 1 year in the last 10 have the same voting rights as an ever present like Everton? Maybe, maybe not.
Should Everton get relegated should they lose all voting rights immediately?
Maybe it should be proportional. Maybe you get 1 vote for each of the rolling last 10 years you were in the premier league. So City, Spurs, Chelsea, Everton, Newcastle, Palace would all currently get 10 votes each whereas Burnley would get 8 votes and Forest would get 2 votes.
Not sold on that idea, but it's still the case that no one team gets more than 1/20 of the total vote.
