I believe its because there is no set quota for non res. Say there are 100 tags for a specific hunt. Landowners get 15 percent so there would be 85 tags left for the regular draw. Residents could draw all 85 tags if they had the most preference points. Non res aren't guaranteed 35 percent of the tags. They can draw up to 35 percent though. And of course there are slightly different numbers if its an 80/20 unit.
On another note, it looks like the archery deer hunts are creeping also.
