How many points is a win worth this weekend? Here are unofficial Strength Index numbers through Week 1 of play

Some teams have played one game, many have played two. It’s still too early in the season to look at playoff standings, but we’ve got a look at the entire state’s Strength Index numbers through Week 1 of play.

Strength Index is what’s used to determine a team’s OSI – Opponent Strength Index – which is 60% of the UPR formula that seeds the state’s playoffs for public schools. A team gets the full SI value of an opponent for a win, half the value for a loss, and they’re averaged out over the season to get the final OSI value.

Strength Index changes with every game played. The winning team goes up or down by 1/5 of the difference between the SI of the two teams, and how they did comparatively.

For example, if Team A rated 80 plays Team B rated 73, the difference is 7 points.

• If team A wins by 7, the difference is 0, and the values do not change
• If Team A wins by 12, the difference is 5. Team A goes up 1 to 80, Team B goes down 1 to 72.
• If Team B wins by 3, the difference is 10. Team B goes up 2 to 75, Team A goes down 2 to 78.

Below is a full list of Central Jersey Sports Radio’s unofficial calculations of the Strength Index for all New Jersey NJSIAA member teams. Note that out of state games are not counted for power points, nor are they considered for SI changes or OSI in playoff seeding.
