In October of 2018, Groger Ranks was founded as an alternative method of ranking teams that took powers into account in addition to PPB. Today, it has expanded to encompass podcasts, polls, and more.
The rankings use the following formula:
This formula is designed so that a team that gets 8 adjusted powers per game will get 50 points for the power section, and a team with 24 aPPB will get 50 points in the bonus section. The bulk of the formula means that teams that get 24 aPPB and 8 adjusted powers per game (which has been discussed as the minimum threshold for a team to be a national contender) will score 100 points in this area. Negs per game are then subtracted to differentiate between teams of similar skill level.
The rankings include any teams that have played appropriate tournaments this year (which have both proper power and PPB stats) and have met the requirement of 10 aPPB. A-Sets, MSNCT, and other novice sets were not included because they are not good indicators of performance at the high school nationals level.
Every set is adjusted based on difficulty so that power and PPB stats can be compared across difficulties. You can read more about our adjustments in this analysis article.
The rankings aren’t based solely on the best performance of a team, but a combination of performances, all weighted in importance. You can read about our weighting methodology in this article.
