Here's an idea to make attendance figures in sports box scores more relevant.  The box scores usually indicate the attendance that was present at the event (ie: 17,145).  What would render this more relevant and interestinis the percentage of the stadium or arena capacity that this attendance figure represents.  So let's say at a New York Met's home game there were 17,145 people present, and the stadium has a capacity of 45,750, then the attendance firgure for this one game would be shown as (17,400) (37.48%).
