3A-A multi-year improvement

Unlike 4A, the teams in classes 3A-A play a lot of connecting games. Thus, rankings for 3A-A teams should be more accurate than 4A team rankings. Given this proposed improved level of accuracy, how many teams have improved in both 2008 and 2009?

There are 243 teams in the 3A-A pool. Of this number, 52 teams improved in both 2008 and 2009. Fifty-two is a lot to list, so I won’t. Of these 52 teams, 15 teams additionally improved in 2007, three consecutive years of improvement.

Explanation of following charts:

Akron-Westfield finished #163 in the BCMoore Rankings in 2006 (06).
Akron-Westfield finished #61 in the BCMoore Rankings in 2009 (09).
