The TT factor for the 2011 college football postseason is 32 (stable) |
||||||
In a college football week, when high ranked teams lose
to low ranked and unranked teams, the media calls it a wild or topsyturvy week.
To quantify this hype, we developed a metric called the TT factor.
The TT factor for the current week is calculated based on the difference between the AP rankings in current week and the previous week. The TT factor can vary between 0 and 200; the lowest TT factor recorded so far is 8 and the highest is 72. Based on statistical analysis of the TT factors for six recent seasons, we consider a week in which the TT factor is greater than 54 to be highly topsyturvy and if less than 30 to be very stable.
