What do rpi rankings mean

How is strength of schedule calculated? What is BPI rank? BPI is meant to be the best predictor of a team's performance for the rest of the season. BPI represents how many points above or below average a team is. How is volleyball RPI calculated? The RPI formula is 0. The RPI formula puts so much emphasis on strength of schedule that a team's wins and losses can be lost in the mix.

Rather, it does a calculation for each opponent and then averages the results. The NCAA uses this averaging method to take into account the fact that different opponents play different numbers of games: By averaging, the NCAA assures that each opponent's contribution to Team A's Element 2 is weighted the same as each other opponent's contribution. Also, if Team A plays multiple games against an opponent, then the opponent's winning percentage against teams other than Team A is counted multiple times in determining Team A's opponents' average winning percentage.

Element 3 of the RPI measures a team's opponents' opponents' average winning percentage using, for each Team A opponent, the same method to determine that opponent's opponents' winning percentage as used in computing Team A's Element 2. Calculation of RPI. Once the NCAA has calculated each of these Elements, it combines them to determine the variously called "basic" or "normal" or "original" or "unadjusted" RPI.

The formula for determining the Unadjusted RPI is:. In effect , however, this is not true. The following table shows why:. This table shows, for each year, the high and low of each of the three RPI elements.

It then shows the difference spread between the high and low for each element. The bottom row of the table shows the averages for the element highs and lows, the element spreads, and the element effective weights. As the table shows, the spreads for the three elements grow smaller when progressing from Element 1 to Element 3.

The reason for the diminishing spreads is obvious, if one thinks about it. The computation of Element 1 looks at one team's record. Individual teams' records reasonably can range from undefeated an RPI Element 1 of 1. For Element 2, the computation looks at about 19 teams' records and averages them out. Teams, on average, play about 19 games in a season. With this many teams' records being used for Element 2, nearly all of the teams are going to have some wins and some losses, so the high Element 2 is going to be less than 1.

Similarly, for Element 3 the computation looks at about 19 x 19 teams' records. This inclusion of a very large number of teams' records produces Element 3 numbers that are even less at the extremes than for Element 2, making Element 3's maximum reasonable and average spread smaller than for Element 2 and much smaller than for Element 1.

Element 1: Element 2: Element 3: If you are having trouble understanding this, think of fruit salad. To do that, I compare the fruit sizes and figure out that the right ratio of ingredients is 1 cantaloupe to 2 oranges to 1 kiwi fruit. Winning percentage Factor I only receives a 25 percent weighting although its real strength is larger. There always is a far wider gap in the rankings between the top and bottom teams in this category than between the first and last in Factors II and III.

The Committee sets the basic structure for the bonus and penalty adjustments. In setting the structure, the Committee typically tells the staff how many positions it wants a team to rise in the rankings for a good result or descend in the rankings for a poor result. The staff then identifies the adjustment amount that will achieve the intended rise or descent.

Before then, the data were kept confidential within the committees. The three component factors which make up the RPI are as follows:. For the men, beginning in , and for the women, beginning in , home wins are weighted 0. How heavy is Connor McDavid pounds?
