About the TWISTR Ratings

The TWISTR Ratings are an iterative least-squares, score-based ratings system built in the spirit of an Elo model. Team ratings are agnostic to the final result of a game, as only the scoring margins are important when rating teams. No additional benefit is provided for a win or penalty for a loss. The TWISTR ratings for VOLLEYBALL incorporate two key concepts:

The RATING represents the number of sets a team would be favored by against an average opponent. Teams with a positive RATING are considered better than average, while teams with a negative RATING are considered worse than average. The RATING can be thought of as a composite of the INDEPENDENT (INDY) rating, in which the time a game was played does not matter, and the FORECASTER (CASTER) rating, where recent results are weighted more heavily.

Both the STRENGTH OF RECORD (SoR) and Z-SCORE (Z-SCR) are resume ratings - SoR only considers a team's win-loss record and is independent of margin of victory, while Z-SCR is a blend of RATING and SoR.
