Kansas High School Football Power Rankings
How PPI
works
For those of you not familiar with this unique football power
ratings, here's a brief summary.
The
PPI statistical formula uses mathematical equations to rank all Kansas high
school football teams in their respective classes. Records, points scored
(offense) and points allowed (defense) also are listed each week for all teams
eligible for district competition.
What
distinguishes PPI from other computer rankings is the starting point. All teams
begin the season at the same PPI starting point as the rest of the teams in
their class. Class 6A teams begin at 85, Class 5A teams at 80, Class 4A teams at
70, Class 3A teams at 60, Class 2-1A teams at 50 and all eight-man teams at 40.
There is no given rating based on the previous season. No guessing how strong a
team should be at the start of the season. All teams earn their ratings from
their performance on the field for that season. Offense, defense and strength of
schedule are the main factors that determine a team's PPI. A victory over a
higher-rated team will be worth more than blowing out a weak team. Running up
the score past a certain margin will not increase a team's PPI. Also, a victory
over a team above you won't necessarily move you past that team. It all depends
how close your ratings were and how decisive the win
was.
