2004-05 formulaIn response to the controversy created by the voters in the AP poll naming USC as the No. 1 ranked team at the end of the year, [1] the formula was completely rewritten. Supporters of USC and the media in general criticized the fact that human polls were not weighted more heavily than computer rankings and this criticism led to the new math.
AP Poll: A team's AP Poll number is the percentage of the possible points it could receive in the poll. As an example, in the final regular-season poll of 2003, LSU received a total of 1,580 out of a possible 1,625 points from the voters, giving them an AP Poll percentage of 97.2.
Coaches' Poll: This is calculated in the same manner as the AP Poll number. For LSU, their final regular-season number in this poll would have been 99.4 (1,516 out of 1,525 possible points).
Computer Average: The BCS used six ranking systems, with the New York Times opting not to participate. In the calculation, the highest and lowest ranking for each team are dropped. Then, it will give a team 25 points for a Number 1 ranking in an individual system, 24 points for Number 2, and so on down to 1 point. Each team's set of numbers is then added, conveniently making the number compatible with the percentages from the two polls. To address concerns about loss of the schedule strength factor, the description of the computer rankings explicitly included schedule strength as a consideration. For USC, dropping their highest and lowest computer rankings would have left them with four third-place finishes, worth 23 points each for a total of 92, while LSU would have had four second-place finishes for a total of 96. The BCS averaged the three numbers obtained above, divided the result by 100, and converted it to a decimal fraction. This system placed twice as much emphasis on human polls than computer rankings, and made it highly unlikely that the top team in both human polls would be denied a place in the title game, as it happened in 2003-04.
