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.
