Weighted Yardage Performance Poll (WYPP): This poll essentially focuses on offensive and defensive efficiency weighed against your game-by-game Strength of Schedule (SOS).  For the sake of simplicity, average yards gained and allowed per play are used to determine rankings. The poll applies the Pythagorean formula 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 PPP score. The result is then averaged with your SOS score (this makes sure your PPP ranking is not inflated from beating up on weaker teams) to get an adjusted performance score. The way this works is 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 Performance 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 multiplied against the % of plays to determine the true average offensive yards gained. (OPA X %of plays) + (ORA X % of plays)
• DEF: Team passing yards-opponents per play average (DPA) and team rushing yards-opponents per play average (DRA) are multiplied against the % of plays to determine the true average defensive yards allowed. (DPA X %of plays) + (DRA X % of plays)
