See Strength of Schedule for an explanation. There are three sos calculations: the 1st averages the opponents computer rating based on computer margin of victory "Reg In" and "ROM", the 2nd is similar to the first but instead of a simple average, it weighs games against stronger teams more heavily, and the 3rd is based on the RPI SOS formula used by the NCAA. This factor is not used in the power rating calculation and uses only the top ten (rpi based) teams.
Congratulations to 2013 League Champions - Haverford School (InterAC) and Shipley School (FSL)
