There are numerous different NFL Rating systems and computer ratings. The rankings differ far and wide, from ratings that solely focus on how much you a beat team by, and other rankings who don’t factor margin of victory at all. I took a composite of 33 different NFL Ratings that I could find on the internet, to create power ratings for Week 11.
To calculate the composite I averaged the ratings of each team to get the mean, then I took the median of each team’s ratings. I then averaged these two together. I did not solely use the arithmetic mean due to the fact it can be influenced by outliers while the median is not.
I then used a normalization statistical method called future scaling. I have used future scaling in previous articles, such as my Power Ratings of International Soccer Countries going into the World Cup. The scaling here is done for more arbitrary reasons to give the team’s a rating from 0-100. Therefore the formula for the composite is as follows:
(32-((∑(Team Ratings)/33)+Median*)/2))/(32-1))*100
*Median= (Rank the Values from highest to lowest, the middle number is the median, in this case, it was the 17th rating)

*Transitive W-L% is a simple ranking system to rate teams based on who they have beat and who they have lost to. The result of the game (Win or Loss) and the opponent’s Wins and losses are the only things that matter.
Formula: (Cumulative Wins of Team’s Beat)/(Cumulative Wins of Team’s Beat + Cumulative Losses of Teams lost to)
E.G.: Team A beats, Team B(1-2), Team C(2-1), and loses to Team D(1-2). They have 3 transitive wins and 2 transitive losses. Their rating is 3/5=.600
