Sonny Moore's Power Ratings Description

Sonny Moore's Power Ratings were devised in 1974. This hobby began so I could make a comparison of any two teams in a given sport, so as to get an indication on which team would win and by how many points if a game were played between them (predictive intention). I also wanted a systematic ranking of all the teams in order from best to worst based on this comparison, as if all the teams were to play against one another. A team's power rating reflects how a team has performed from all the games played, not just one or two, taking into account wins and losses, the opposing teams' power ratings and the actual score difference of the games played. This explains why team A may have a higher power rating than team B, even though team B may have beaten team A or have a better won/lost record. The ratings are compiled by using only statistical and historical data. The most recent games played are more meaningful in compiling the ratings. Only games played against the teams in the ratings are used to formulate the power ratings. A diminishing returns principle is used to prevent higher rated teams from gaining power rating points and moving up in the rankings when the victory margin is being run up against a weaker team. Beginning 2000, a team's power rating value will be displayed atleast two decimal places instead of rounding off to whole numbers, so as to give a more precise and greater distinction in the ratings by reducing identical values amoung the teams. This will in turn give a more accurate ranking within each sport.

* Earl Nall has compiled data comparing ratings that use MOV (margin of victory, or the score difference) verses not using MOV.
