regular season schedules (please see requirements on page 4). Please note that the Strength Index numbers
will be calculated and rounded to the hundredths decimal place (i.e. two decimal points).
For any new program that does not have a 2021 Strength Index rating, they will be assigned a starting SI of 20
points for the season. For any new cooperative sports program, the starting SI rating will default to the highest
end of season SI rating from the most recent prior season of the participating teams. When an existing
cooperative sports program is dissolved, each school’s stand-alone SI rating will be determined by the NJSIAA.
For instance, Team A’s BPI was 90 at the end of the season. Therefore, 90 minus 60 equals 30 so Team A will
move down by 1/3 of 30 (or 10 points) to a starting SI value of 80 points. Team B’s BPI was 39 at the end of the
season. Therefore 60 minus 39 equals 21 so Team B will move up by 1/3 of 21 (or 7 points) to a starting SI
value of 46 points.
All teams with a Strength Index of 0 or a negative value at the end of the 2021 season will have a starting SI
rating of 20 points…no team will start the 2022 season with a SI rating of less than 20 points. For purposes of
the OSI calculation only, no opponent will be valued at less than a 20-point SI rating.
For all games up to and including Week 7, a team’s SI will move weekly based on the game results compared to
the expected outcome of each game. The expected outcome of a game is determined by the SI values prior to
the start of the game. For every point off the expected outcome, teams will move by 1/5 (or .2) in the appropriate
direction depending on the game result. However, please be reminded that a school’s own SI rating has no
bearing on its OSI calculation that is included in the United Power Ranking system.
For example, team A’s SI is 70 and Team B’s SI is 50…the expected outcome of the game is a 20-point
difference in favor of Team A.
1. If the game result is a 20-point win by Team A, then there is no change in either Team’s SI.
2. If the game result is a 10-point win by Team A (10 points less than the expected outcome), then Team A will
move down by 2 points (10 points X .2 = 2 points) and Team B will move up by 2 points.
3. If the game result is a 40-point win by Team A (20 points more than the expected outcome), then Team A
will move up by 4 points (20 points X .2 = 4 points) and Team B will move down by 4 points.
4. If the game result is a 5-point win by Team B (25 points more than the expected outcome in favor of Team
B), then Team B will move up by 5 points (25 points X .2 = 5 points) and Team A will move down by 5
points.
The Strength Index ratings will be final on Monday, October 17, 2022; however, please note that all games
played will count towards playoff qualifications. The final Strength Index ratings will be used in the average
calculation that will determine a team’s OSI rating which is 60% of a team’s UPR. Therefore, a team’s OSI rating
will be updated weekly during the season, but the value of the opponent’s SI will be updated and final on
Monday, October 17, 2022.
Forfeits:
When a forfeit win is awarded to a school prior to the game, the affected school must accept the forfeit unless
they can replace the game. The SI value for each school will remain unchanged and the SI values will go
unchanged. The substituted game must be played the same week to replace the forfeit. If a team cannot play,
for any reason, they must accept a forfeit loss. The exception of natural disasters will be determined by the
NJSIAA.
Once a school starts its regular season competition, then all scheduled games are expected to be played. No
scheduled game can be "mutually dropped" by both teams. Games must either be played, or a forfeit be
declared. If there are extenuating circumstances that would prevent two schools from playing a scheduled
game, then the League or Conference must submit a written summary of the circumstances that necessitated
the need to mutually drop a scheduled game.
When a forfeit win is awarded to a school after the game is played (i.e. due to a rule infraction such as an
ineligible player), the SI values for the forfeited game will not be recalculated. However, the OSI will be updated
to reflect the new win-loss result.
