Power Index

A weekly 1-18 league ranking that accounts for wins, losses, run differential, and — most importantly — who you've actually played. Your record is only half the story.

How the Index works

The Power Index blends three components into a single 0-100 rating. Each week we recompute from fresh data scraped from the league standings page.

RATING = 40% × ADJUSTED WIN % + 35% × AVG RUN DIFF + 25% × ITERATIVE OPP-ADJ RATING

Adjusted Win % combines your record with your opponents' records (RPI-style). Iterative Rating solves for each team's true strength by factoring in the strength of who they beat or lost to. In weeks 1-3, run differential is weighted heavier since SOS hasn't stabilized yet.
