The YAM2 Ranking is based on a simple mathematical formula which is designed to measure team accomplishment over the course of the season. It uses Win% and a strength of schedule (SOS) metric, in similar fashion to the Rating Percentage Index (RPI). However, YAM2 differs from the RPI in one significant aspect. In order to prevent inverse effects, the ranking metric is a product of Win% and the SOS metric, whereas in the RPI metric it is a sum. Thus, a loss by a team will almost always produce a decrease in the YAM2 metric, and a win will almost always produce an increase in the YAM2 metric. The magnitude of these effects will be influenced by the strength of the opponent. (It is also worth noting that the actual change in ranking *placement* for any given team, as opposed to the ranking *metric*, will be strongly influenced by the simultaneous changes in records for "neighboring" teams in the ranking table.) YAM2 = Win% * SOS The SOS metric used in YAM2 is the same as that used in the original RPI weighting factors: namely 2 parts Opp% added to 1 part Opp-Opp%. In this implementation the SOS metric is normalized to the toughest schedule for convenience. The table below is best viewed using a constant pitch font. YAM2 RPI Norm. YAM2 Rank Rank Win% Sched.
