For example, if the cut-off point is four years, that means a game played exactly four years ago will be given no weight, a game played three years ago will be given one-quarter weight, a game played two years ago will be given one-half weight, a game played one year ago will be given three-quarters weight, and a game played yesterday will be given almost full weight. 10, 2020. The ratings are very carefully designed such that a team will not be penalized (nor rewarded) if its players make their home in club leagues other than the "Big 4.". But AGS and AGA are in turn determined, in part, by referencing the OFF and DEF factors of a team's opponents. After about 20 to 30 iterations, this estimate becomes stable down to several decimal places, and we are able to calculate reliable OFF and DEF factors for any given team on any given date. As a result of this, we have a single OFF90 and DEF90 rating for each player in the database. The OFF and DEF ratings we obtained for each team in Step 2 is only half of the SPI. Once we have calculated this recentness factor, in addition to the competitiveness coefficient, we can "roll up" (take a weighted average) the AGS and AGA figures that a team receives in each match to produce overall OFF and DEF ratings. In some cases, detail on each team's lineup is not available for a particular match.
