The Market Potential Data is based on MRI's 'Survey of the American Consumer.
In the Past Esri use to define a "super fan" as any respondent that responded by selecting either 8, 9 or 10.
We recently changed our methodology and are currently using 10 of 10 as being a sports "super fan".
See below image on what the survey respondent sees when filling out the survey:
