Funny how that works out: more wolves, less elk and less wolves, more elk.
Apparently it is rocket science since they are attributing much of the wolf decline to lack of food, disease, and pack disputes.

(more wolves, less elk) Then had to kill each other off, starve and caught disease from malnutrition. Enough died off that the elk could rebound. (less wolves, more elk)
http://www.nps.gov/yell/learn/news/02042015.htmThe Northern Yellowstone Cooperative Wildlife Working Group conducted its annual winter survey of the northern Yellowstone elk population on January 20, 2015. The survey, using three airplanes, was conducted by staff from the Montana Department of Fish, Wildlife & Parks and the National Park Service. Staff counted 4,844 elk, including 1130 elk (23%) inside Yellowstone National Park and 3,714 elk (77%) north of the park. Survey conditions were favorable across the region.The 2015 count was 24% higher than the 3,915 elk counted in 2013 and was the highest since 6,037 elk were counted in 2010. Survey conditions in 2014 were poor and resulted in an inaccurate count.
Sure, wolf killing wolf first, multiple diseases (distemper etc. and mange, a mite) second and other causes (hunting) third but I see no mention of dispersion. Some of the DNA studies on Washington wolves show imported Alberta genetics and with the huge numbers in the park early in the process dispersion would be the major reason for decrease in the park. With the mileage numbers we have seen from collared individuals, Washington should be considered normal range for Yellowstone wolves. It is not unusual for them, it is what they do.
