2009 boys PA East PIAA              UPSETS ARC
 
Upsets are listed in order of magnitude based on score and power
 rating. An upset occurs when a team of lower power rating beats 
 a team of higher power rating. Home advantage is not included. 
             
 An upset requires the Power Ratings of the two teams to be at
 least two points apart.

 Upsets may disappear as the season progresses because as power
 ratings are adjusted, the difference in ratings between two
 teams may fall below two points.
