NFL W13 Betting Predictions & Simulations
The ISW employs its proprietary power rating system each NFL season beginning with preseason power ratings that are adjusted weekly according to team performance against the spread (ATS) as well as margin of victory throughout the season. Starting in Week 10, The ISW commenced an experimental multivariate power ratings approach.

New Power Ratings Methodology incorporates the following season-long team data: yards per point margin (YPPM), net yards per play (NYPP), average scoring margin (ASM), winning %, average performance against the spread (ATS), yards per pass attempt (YPPA), points per play (PPPLY), and pythagorean winning % (PYTH). We run a weekly correlation calculation to determine the weights of each variable as correlated to pythagorean winning %, which we believe is the purest descriptive statistic of a team’s relative strength.
