Bowl Championship Series explanation
Team percentages are derived by dividing a team's actual voting points by a maximum 2850 possible points in the Harris Interactive Poll and 1575 possible points in the USA Today Coaches Poll.
Six computer rankings calculated in inverse points order (25 for #1, 24 for #2, etc.) are used to determine the overall computer component. The best and worst ranking for each team is dropped, and the remaining four are added and divided by 100 (the maximum possible points) to produce a Computer Rankings Percentage. The six computer ranking providers are Anderson & Hester, Richard Billingsley, Colley Matrix, Kenneth Massey, Jeff Sagarin, and Peter Wolfe. Each computer ranking accounts for schedule strength in its formula.
The BCS Average is calculated by averaging the percent totals of the Harris Interactive, USA Today Coaches and Computer polls.
