Standings as of 2019-10-01

The Gonzalez System is a computer ranking model similar to Elo and is a rating exchange system based on research performed by World Rugby. It has been adapted by the NCDA to the demands of College Dodgeball, but can be tuned and customized endlessly to incorporate accurate data. It has been used to help determine seeds for the Nationals bracket since Nationals 2014, and was used exclusively for the Nationals 2017, 2018, and 2019 bracket.

Technical Upset Spotlight

A technical upset in the Gonzalez System is when a lower rated team defeats a higher rated team. The overall success rate of the system is currently 80.62% based on 354 technical upsets in 1847 ranked matches played since 2010-09-25.

There were 10 technical upsets since our last standings update.

Technical Upsets in September

ZM: Think that we had a lot of technical upsets this past month? You’re right. 11 technical upsets in the first 31 ranked matches is about ~14% difference than the past six seasons.

In 2011, 2012 and 2013 we had only a handful of matches in September. We’ll exclude those for the purposes of comparison of later seasons in which teams started to play earlier into their school year.

2014 – 3 technical upsets in 16 ranked matches (81.25% success rate)
2015 – 4 in 32 (87.50%)
2016 – 5 in 17 (70.59%)
2017 – 10 in 34 (70.59%)
2018 – 8 in 35 (77.14%)
2019 – 6 in 33 (81.81%)
2020 – 11 in 31 (64.52%)

While a “significant upset” can often be a floating definition for the Content Team, an important measure of the system is whether a technical upset is statistically significant. By design, the system should be able to ensure these statistically significant upsets are few.

We generally settle that upsets beyond the second deviation (95.45%) would include technical upsets with an initial rating gap greater than -6.685 (1.668 exchange), spanning all the way up to -9.848 (1.985 exchange). There are 16 statistically significant technical upsets in the second percentile, of 354 technical upsets. These are the current numbers, updated to include the weekend’s two significant upsets, presented as the first two matches below.

There are five significant technical upsets that occurred in the first matches of September:
2020: JMU def Towson 4-3 OT at this weekend’s Double Header
2016: MSU def GVSU 1-0 at Impact at IM West
2018: BGSU def MSU 4-2 at Early Access
2020: OSU def BGSU 6-2 at this weekend’s Buckeye Invitational

The Buckeyes took home the most points this weekend and rightfully so. With three wins, two of which were upsets, it should come at no surprise they moved up as much as they did. Ohio also had a great weekend, finishing 3-0 and getting a leg up on Miami in their first matchup of the season. Cleveland State rounded out the biggest gainers from the Buckeye Invitational thanks to two upset wins over Akron and Kent.

Where there are big winners there are also big losers, however. BGSU, Kent, and Akron all took significant damage in their Gonzalez ratings after lackluster performances. After a pivotal win over Michigan State in their first tournament of the year, BGSU felt the effects of missing some of their top players such as Owen Sill. Kent and Akron both saw significant losses this offseason by graduating talented Seniors. This year was expected to be a bit of a down year for both programs. With more experience for their young players, expect both teams to hit their stride a bit more by November.
