NR are not given their own allocation of tags in the deer/elk draws, and can only draw tags by preference in any specific hunt code if they have preference point superiority to the residents who applied. Due to point creep over the years, in actual practice, more than enough NR's apply in all the high-demand hunt codes who have PP superiority over resident applicants. Thus, NR applicants will always meet the NR allocation ceiling in the regular part of the public draw. Therefore NR cannot draw any tags in the Hybrid portion of the public draw because by rule, NR are not allowed to exceed the 20% allocation ceiling.
What appears to be anomalies in the regular portion of the draw, usually is caused by group applicants. Say the NR ceiling is 3 tags for a particular hunt code. And the first 2 tags go to the highest point holders. The final tag cannot go to any group applicant because there is only one tag left. So the tag keeps dropping down through the next lower point classes until a single applicant is found who did not apply as a group. I don't know if this was the case for the Unit 66 4th rifle applicant cited above, or if it was something else, or a mistake. If curious enough, you could always ask the supervisor of the licensing department, they are usually very helpful.
