Usage: To be used in all self-contained District IV Team Championship sports. To be used in sub-regionals where agreements with other districts have been reached.
The power rating will be a combination of the team's weighted winning percentage (TWWP) and their opponents' weighted winning percentage (OWWP). The power rating would be the sum of 59 percent of the team's TWWP and 41 percent of the team's OWWP.
STEP 1: CALCULATING TEAM WEIGHTED WINNING PERCENTAGE (TWWP)
The TWWP is based on the results of all games that a team plays. It values wins and losses by the classification of the opponent. The TWWP is calculated by dividing the WEIGHTED WIN VALUE by the sum of the WEIGHTED WIN VALUE and WEIGHTED LOSS VALUE.
TWWP = 4.95/(4.95 + 5.55) = 0.471428
All PIAA opponents and all non-PIAA opponents who are part of a State Association will count in calculating a team's TWWP and OWWP using the classification system above. Teams that are non-PIAA and not part of a State Association will NOT count in calculating the Power Rating.
STEP 2: CALCULATING OPPONENTS WEIGHTED WINNING PERCENTAGE (OWWP)
The OWWP is calculated by totaling the weighted win values and weighted loss values of all of the team's opponents; then, dividing the total of the weighted win values by the sum of the totals of the weighted win values and the weighted loss values. If you play your opponent more than once, their totals will be included for each time they are played.
OWWP = 61.5/(61.5 + 35.6) = 0.633367
CALCULATING POWER RATING
The Power Rating is the sum of 59% of the TWWP and 41% of the OWWP. This number will not be over 1.000.
TWWP: 0.471428 * 0.59 = 0.278142
OWWP: 0.633367 * 0.41 = 0.259680
0.278142 + 0.259680
POWER RATING = 0.37822
