They would obviously be better off training instead.The majority of people who like to run field trials do not qualify for the Nationals and and want to run their dog.
I speak from experience on that.
Last weekend I heard complaints about low entry numbers and the club going in the red for the event, followed by "that dog is already qualified, he/she shouldn't have entered."Their was a tradition that once a titled dog had qualified for the nationals it did not run weekend trials.
If only non-qualified dogs and handlers that intended to go to Oregon entered, there may not have been enough dogs running to award championship points.
