Record
A team's winning percentage (Pct) is calculating by adding its wins to half its ties and dividing by the total number of games played. I.e., a tie counts as a half a win and half a loss, which is true for all the rating systems considered here.
RPI
The Ratings Percentage Index, a linear combination of a team's winning percentage (25%) with the winning percentages of their opponents (50%) and their opponents' opponents (25%), which is the most important of the NCAA's selection criteria. More information can be found on our RPI page.
KRACH
Ken's Rating for American College Hockey is an application of the Bradley-Terry method to college hockey; a team's rating is meant to indicate its relative strength on a multiplicative scale, so that the ratio of two teams' ratings gives the odds of each of them winning a game between them. The ratings are chosen so that the expected winning percentage for each team based on its schedule is equal to its actual winning percentage. The Round-Robin Winning Percentage (RRWP) is the winning percentage a team would be expected to accumulate if they played each other team an equal number of times. More information can be found on our KRACH page.
PWR
The PairWise Rating is determined by performing PairWise Comparisons (PWC) according to the NCAA's selection criteria between all teams with RPI's at or above .500 and totalling the number of comparisons each team wins. More information, including a breakdown of comparisons won and lost according to criteria, can be found on our PWC/PWR page.
