We limited this analysis to the 20 inch class to determine who benefits most from the qualification changes from 2013 to 2014 for the AKC National Agility Championship.
This first chart shows the 20 inch dogs who qualified for the 2013 AKC NAC. The red points indicate dogs who would NOT have qualified had the 2014 rules been in effect. These dogs in red are hurt by the qualification change. The distribution indicates that slower dogs are more likely to not qualify under the 2014 rules; 62% of these dogs in red went slower than the average YPS for the group.
This second chart shows the 20 inch dogs who would have qualified for the 2013 AKC NAC if the new qualification rules had been in effect. The green points indicate dogs who qualify under the new rules, but did NOT qualify under the 2013 rules. These dogs in green are helped by the qualification change. The distribution indicates that faster dogs are more likely to qualify under the 2014 rules; 93% of these dogs in green went faster than the average YPS for the group.
The video below shows a few other interesting trends, in addition to summarizing the information above.
