Gonzalez System Home Court Advantage Update

The Executive Board had voted on 2016-12-10 to move exclusively to the Gonzalez system, which will determine the seeds for the Nationals 2017 tournament bracket. During peer review with the Content Team, the value of Home Court Advantage was questioned and initiated a full review on home court advantage in the NCDA. This review was based on objective data from past matches (1114 ranked matches as of 2017-02-10) and determined that +1 was more appropriate than the +3 used by the system.

HCA +3 = 231 technical upsets of 1114 matches (79.26%)
HCA +1 = 208 technical upsets of 1114 matches (81.33%)
Variance: 23 in 1114 (2% or about 1 in 50)

The Executive Board has voted to update the Home Court Advantage modifier to +1.

Motion to adjust the Home Court Advantage variable from the current +3 to +1 point for the home team. This increases the accuracy of the system and is more realistic indication of home court advantage.

5/5 approve, with assent of Director of Nationals. Motion caries 2017-02-06 22:40 CST.

The Gonzalez system will use +1 point in the case of home court advantage and the system variables are frozen for Nationals 2017. The Gonzalez system will determine the seeds for Nationals 2017 tournament bracket. The current success rate with this variable is 208 technical upsets of 1114 total ranked matches (81.33%).
