Hey guys, not sure how I missed this subforum, but I've been posting some of my stats pages in the games' pbp threads. Anyways I saw this subforum and thought you guys may get a kick out of the website that I developed/update http://www.powerstats101.com/ It's a unique statistical system that focuses on the 2 most important aspects of the game: what happens at the change of possession and what happens near/inside the box. We calculate momentum differently than the media, who just relies upon possession or touches figures, which can contain worthless defensive possession or useless touches. Hope you guys enjoy it!
One thing that really needs to be more clear: are your graphs tracking a running total, or "last five minutes", or something different? The only thing I've been able to figure out is that the team's final power rating is the sum of the values at 15-minute intervals.
