Computer Ranking - Weighted PPP Ranking (WPPP)
Weighted PPP Ranking (WPPP): This ranking considers your drive performance efficiency and your yardage efficiency weighed against your game by game SOS% (gbgSOS%) to determine the overall efficiency of your PPP execution. The game by game SOS% (gbgSOS%) is determined by averaging the SOS% calculated for each game. Each game SOS% is based on your opponent's W/L% and their opponent's strength of schedules. How is this SOS% applied as a weight? Your SOS is compared to a .500 SOS to determine your SOS weight % (e.g. if you have an SOS of .600, your weight % would be 110%, thus slightly increasing your PPP Efficiency score). For the sake of simplicity, average yards gained and allowed per play are used to determine your yardage efficiency. The Pythagorean formula is applied to a team’s average offensive yards gained per play (OFF) and average defensive yards allowed per play (DEF). The formula OFF2.37 / (OFF2.37 + DEF2.37) is used to determine your score. OFF and DEF are determined as follows:
- OFF: Team passing yards per play average (OPA) and team rushing yards per play average (ORA) are averaged to determine the average offensive yards gained. (OPA + ORA)/2
- DEF: Team passing yards-opponents per play average (DPA) and team rushing yards-opponentsper play average (DRA) are averaged to determine the average defensive yards allowed. (DPA + DRA)/2
Your drive performance efficiency is based on how many points you score per drive and how many points you allow your opponents to score per drive. Drives are determined by focusing on the stats associated with the endings of drives (i.e. turnovers, TDs, punts/blocked punts, 4th down fails/stops and FG attempts). The poll applies the Pythagorean formula to a team’s "points for" per drive (PF/D) and "points against" per drive (PA/D). The formula PF/D^2.37 / (PF/D^2.37 + PA/D^2.37) is used to determine your Drive Performance score. PF/D and PA/D are determined as follows:
- PF/D: Offensive drive efficiency is calculated by dividing the team's total "points for" by the total number of giveaways, TDs, punts, 4th down fails and FG attempts.
- PA/D: Defensive drive efficiency is calculated by dividing the team's total "points against" by the total number of takeaways, opponent's TDs scored, opponent's punts, opponent's 4th down fails, and opponent's FG attempts.
