VolleyMob Efficiency Rankings: Updated Headed Into the Final Four

  0 Derek Johnson | December 11th, 2018 | College - Women's Indoor, News, Rankings

We have developed a new metric to rank a team’s performance over the course of the season. It’s a first draft model that will likely need some tweaking, but as of now it features a collection of record, winning percentage, strength of schedule, sets differential, point differential, hitting percentage and opponent hitting percentage – all with different modifiers.

Last week we released teams’ ratings who made it into the Sweet 16. This week we have updated all of those teams.

Note that the top four sure enough work out to be the four teams left. That’s because Nebraska jumped from six to four. Changes can be seen below. As a reminder though, here’s the ratings of the last five National Champions (with the 2018 results further below).

1 2013 PENN STATE 150.34
2 2014 Penn State 147.31
3 2017 Nebraska 140.78
4 2015 Nebraska 139.9
5 2016 Stanford 130.7

As you can see, the most dominant teams score around 150. A surprise Stanford National Championship team in 2016 was just above 130. Here’s the results to this point this season; keep in mind that with more matches to go teams can still add to their numbers even more. That said, all of the remaining schools would fit somewhere between our last five victors.

Total: Last Week:
1 Stanford 145.93 1
2 Illinois 140.66 2
3 BYU 140.05 3
4 Nebraska 134.3 6
5 Kentucky 132.29 4
6 Minnesota 130.72 5
7 Wisconsin 130.28 8
8 Texas 129.78 7
9 Penn State 127.47 9
10 Marquette 125.73 10
11 Florida 123.43 12
12 Michigan 119.4 11
13 Oregon 118.95 14
14 Washington State 118.94 13
15 Washington 111.59 15
16 San Diego 102.91 16

The formula of how the totals are put together is a sum of the following:

  • (Wins – Losses) x 0.5
  • (Win %) x 10
  • (335 – SOS#) x 0.3
  • (Sets Won – Sets Lost) x 0.1
  • (Points Won – Points Lost) x 0.01
  • (Hitting % – Opponent Hitting %) x 50
