2017 Ratings Comparison

Back by popular demand. Well, I wanted to do it anyway, here is the ranking comparison prior to the state tournaments. This year I’ve collected eight rankings:

WIAA RPI

TeamBrunnhilde RPI

Win-loss

Captured Win-Loss

TeamBrunnhilde Points rating

MaxPreps Rating

Evans Rating

Score Czar rating

The two RPI ratings differ in that TeamBrunnhilde RPI uses available out-of-state records and also utilizes playoff results. The latter three ratings use proprietary rating methods. Win-loss and Captured Win-loss are straightforward calculations one could compute by hand. TeamBrunnhilde Points uses a standard statistical technique.

There is consensus for Boys 3A (Nathan Hale), Girls 1A (Cashmere), and Boys 2B (Kittitas). The other classifications have varying degrees of disagreement between the ratings. While some ratings will have better results than others, all ratings will have notable successes and failures. Like last year, I expect that some ‘sure thing’ game picks (where all rankings agree) will be wrong. The failure rate last year was about 18% for these.

I note that this will be the final year for Score Czar doing high school sports. We’ll miss you. Good luck with your further rating endeavors.
