  1. Re: A football rating system, discussions, ideas I just noticed this thread and couldn't let it pass without commenting. Just two for now: 1. The goal difference is not normally distributed. Using least-squares to arrive at teams' rating metric implicitly assumes normality. This introduces errors. 2. The rating, whichever way arrived at, changes (albeit slowly) during the season. Ignoring that again introduces errors. At first reading I thought the time-dependent change in rating was being effected by the rating update formula, but now I realise that this is only to provide a better estimate of the long-term average of the rating.

  2. Re: Correct score market on Betfair What happens actually depends on the odds for 0-0 at kickoff. For the example you've given where 0-0 starts at 10, if the score is still 0-0 after 10 mins, then 0-0 would move to about 7.7, both 1-0 and 1-1 also generally move lower. It is the higher scores (those with total goals of 3 or more) that move higher. I hope this helps you.
