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.
