OFFICIAL NJ Football Strength Index numbers for all teams following Week Five action

It’s the home stretch of the high school football regular season: two more weeks, and we will be at Cutoff Weekend.

Over the next two weeks, SI values will continue to change. Strength Index is how a team’s OSI is determined, and OSI is 60 percent of the NJ UPR playoff formula, with power points the other 40 percent.

To calculate OSI, teams get 100 percent of an opponent’s Strength Index (SI) value for a win, and 50 percent for a loss, with defeats at the hands of some non-public teams (multipliers) worth more, anywhere from 70 to 80 percent.

One key point to note: heading into Cutoff Weekend, the SI values are locked – but only for playoff calculation. They will continue to be tracked until a team’s season is completely over. But for Week 8, Cutoff Weekend, the numbers after Week 7 will be the set numbers to use for Week 8 calculations so that all that matters is who won and who lost. The numbers won’t change in the formula after Week 8 games are played.

With all of it based on the Strength Index value of teams, once again this week, we’re the only place you can find all of the numbers in one, handy location.

The values below are all Central Jersey Sports Radio’s calculations through games played in Week Five, confirmed with the numbers for every single team in the state on NJ.com, which performs the official calculations for the NJSIAA.

Each week, SI values change based on the final score and the rating of the two teams that played. Here’s an example. SI goes up or down depending on how a team did compared to the difference between the two teams. If Team A (80 SI) plays Team B (60 SI) and Team A wins by 20, there’s no change. If Team A wins by 10, they underperformed by 10 points, and Team B overperformed by 10 points. Team B increases by 2 points to become a 62, and Team A drops to a 78. Team A then gets the full value of Team B for its OSI (62) while Team B gets half the value of Team A (39).

Here are Central Jersey Sports Radio’s UNOFFICIAL Strength Index values after Week Four play:

Note: The NJ.com standings also revealed the SI values of out-of-state opponents for games already played. You can find them by going to a team’s power point calculation page.

Changes? NJ.com says that updates will push every morning at 6 am, if there are any. If an incorrect score has been confirmed and changed, that could affect the SI and OSI of multiple teams, depending on how many games have been played, if any, since the error.
