How Ohio & West Virginia Calculate Playoff Ratings
Football Team Computer Rating System
The procedure used to rate football teams is based upon a system developed by Jack Harbin of Cleveland and used with his permission. The Board of Control has modified the original system. Each team will earn points as explained below.
POINT SYSTEM
On the first level:
Points are earned for each game a team wins.
(FULL VALUE)
Points are earned for each game a team ties.
(ONE-HALF VALUE)
On the second level:
Points are earned for each game a defeated opponent wins.
(FULL VALUE)
Points are earned for each game a defeated opponent ties.
(ONE-HALF VALUE)
Points are earned for each game a tied opponent wins.
(ONE-HALF VALUE)
Points are earned for each game a tied opponent ties.
(ONE-FOURTH VALUE)
Points are earned on the following basis:
Division VI opponent win – 3.5 points; tie – 1.75 points
Division V opponent win – 4.0 points; tie – 2.0 points
Division IV opponent win – 4.5 points; tie – 2.25 points
Division III opponent win – 5.0 points; tie – 2.5 points
Division II opponent win – 5.5 points; tie – 2.75 points
Division I opponent win – 6.0 points; tie – 3.0 points
5.1 First Level Points are awarded for
a. Each game a team wins (full value)
b. Each game a team ties (half value)
c. No points are awarded for game lost
5.2 Second Level Points are awarded as a result of a team defeating or tying an opponent according to the following formula:
a. Defeating an opponent awards to the winner the loser’s first level points.
b. Tying an opponent awards the team one half the opponent’s first level points.
c. No second level points are awarded for losing to an opponent.
d. A divisor is used to determine second level points. It is based on the number of games that opponents have played to date. For each open date that an opponent has had to date, a smaller divisor is used to calculate second level points.
Note: Before any games are played, the computer assumes that the opponents on each school’s schedule will play a full complement of games and assigns the divisor of 100 (10 weeks times 10 opponents=100). After each week of the season, for each open date that occurs for an opponent that a school has played to date, the computer subtracts the divisor by one. In other words, if week five has just been completed and all five of a school’s opponents have played a full complement of games, then the divisor remains at 100, and second level points are divided by 100. If one opponent on a school’s schedule to date has an open date, then the divisor reduces by one to 99, and second level points are divided by 99, and so on. The second level points are then multiplied by the factor 10 in order to move the decimal point higher so that the averages are comparable to those in past years.
5.3 Non-member OHSAA school opponents are assigned a point value based upon male enrollment in grades 9-11. Second level points are awarded based upon the point value of the OHSAA non-member school multiplied times the number of victories by the non-member school (one-half value for a tie).
Note: It is the responsibility of the OHSAA member school to report the weekly results of the games of non-member OHSAA by entering the information into myOHSAA by 10 A.M. on the Monday following the game.
5.31 When the non-member school plays more than 10 regular season games, only the first 10 games will count unless the game with the OHSAA member school is the 11th game in which case the nine games preceding it shall be counted.
5.32 When the non-member school plays less than 10 regular season games, the open dates will be considered an open date except in those states which conduct a state tournament in which case the first round tournament game in those states will be counted, when the first round game is played before the final OHSAA football computer ranking is completed.
5.4 Calculation of Points for Ranking Purposes
Each week, a team’s first level points will be added to the team’s second level points. The total points obtained will be divided by the number of games played to obtain a per game average. Teams will then be ranked within each region based upon their per game average. The margin of victory is not a factor. A win by one point or 20 points counts only as a win. In order to be eligible for tournament participation, a team must play a minimum of eight games. If a team plays less than eight games during the season, the divisor for the end of season rankings will be eight.
