Power Rankings Goal

My Power Rankings are not designed to measure the accomplishments of teams this season. On the contrary, they reflect how good each team is and showed they can be. To calculate how accurate my Power Rankings are, I've compared them to the Week 3 Rankings of ESPN.com. I've calculated the standard deviation of the difference between my rankings and ESPN.com's rankings by taking the average square of each team's difference in the two polls. If I've done a good job, then over the next couple weeks the variance will decrease - as ESPN.com's rankings get more information and thus a more accurate Power Rankings. If I've done a bad job, the variances will increase. Currently, the variance is 960 which means a standard deviation of roughly 5.48

Each team is listed in ascending order of ESPN.com's Week 3 Power Rankings. The square of the difference between ESPN's ranking and mine is given next to each entry.
