Updated Pythagorean Tables

With the Premier League season drawing to a close I thought I’d go back and see what the ‘Pythagorean Expectation’ for the current league table currently looks like. Using the same values as in my previous post of \gamma_1 =1.18 \text{ and } \gamma_2 = 1.23 means we can see if the same teams seem to under or over performing.

This is the league table from earlier in the year.

Below is the current league table I’m working from with about 5 or 6 games to go.

Current League Table

Observations

  • Leicester seem to be unstoppable in real life and despite my prediction of them hitting a blip nothing of the sort has happened to them yet. This is reflected in them having out performed the average teams points total for their goals scored and conceded by a whopping 9.29 pts. This has almost doubled in the last 10 games (they have only lost 1 league game in the last 10 and that was by a single goal)!
  • The other prediction I made was that Tottenham seemed to be under-achieving earlier in the season and that they could challenge for the title. Despite not substantially improving their residual -5.64 to -4.81, they have maintained their good run of form and look like the most likely title challengers to Leicester.
  • Other significant improvements have been made by the likes of Bournemouth and Stoke who have turned their form around to pick up more points than they might have expected to.
  • Everton continue to be having a shocking season based on pythagorean expectation which matches the conventional wisdom about them. In a more typical season based on their goals scored and conceded they should have almost 9 more points.
  • Finally despite my current worries about Watford the maths seems to suggest that they will still be fine in the league this year.
