This website shows the English and Scottish football league tables sorted by the average points per game, then by the number of games played (less is better), then by goal difference and finally alphabetically.
This useful when not all teams in a division have played the same number of games: for a team which has scored ten points from five games to be ranked lower than one which has scored eleven points form eight games is a distortion of the true position: when the former has played eight games, they are likely to have scored sixteen points if they continue scoring points at the previous rate.
Generally, an average of two points per game is good enough to be up at the top. An average greater than two points a game usually indicates a place in the top two or three. A team which is averaging less than a point a game is in danger of relegation.
As an indication, a team averages two points per game by winning all home games and drawing all away games: it averages 2.5 points per game with by winning three out of four games and drawing the other.
The original tables are scraped from the BBC's website.
