Inspired by ClubELO.com, the ELO rating system is a method of calculating and comparing the relative strengths of teams in competition. For every match played, the ELO scores of the two teams are considered, and adjusted for other factors (such as home advantage), to calculate the likelihood of the match result. When the actual result of the game is known, the ELO score is adjusted accordingly, comparing the expected outcome of the game with the actual outcome - so a victory over Manchester United will be worth more points than one over Supermarine. The resulting ELO score can be used to compare the strengths of teams over time, and to project future results based on the current form of all teams.
