They wanted a variety of dogs, so rather than just moving the top 10 dogs up, there can't be more than 3 dogs of any breed in the finals (so if the top 10 20" dogs are all Border Collies, only 3 move up and then the first dog that isn't a BC moves up), and they are requiring one mixed breed in each height. So a judge from New England was the #4 Border Collie in his height - but didn't make the finals, and other dogs who did not do so well did move up.
Fun from a spectating standpoint, but not really the "top" dogs.
