See Win-Loss Factor for an explanation. There are four
 different percentages. The 1st is based on all games, the
 2nd on games played within the division/state, the 3rd weighs games played later in the season more heavily and the 4th
 weighs road wins and home losses more heavily. This factor is not used in the college power rating calculation and only the first percentage is used in the high
 school power rating calculation
