NR are limited to 10% of the total tags: of which half (or 5% of Total tags) can go to NR in the bonus pass. The other half (and any that weren't drawn by NR in the bonus pass) will go to the random 1/2 pass.
Example: Unit 6A: 700 total tags: Up to 70 can go to NR. 35 went to NR in the bonus pass and 35 went to NR in the random pass. You had to have at least 6 points to have a chance on the bonus pass.
Unit 11M 1st hunt: 80 total tags: Up to 8 can go to NR. 3 went to NR in the bonus pass and 5 went to NR in the random pass. You had to have at least 6 points to have a chance in the bonus pass. Resident hunters had more points or were just luckier in the bonus pass because up to 4 could have went to NR in the bonus pass, yet only 3 were drawn. The remaining tag for NR went in the random pass.
Unit 11M 2nd Hunt: 80 total tags: Up to 8 can go to NR. 0 went to NR in the bonus pass and 5 went in the random pass. Residents had the higher points and no NR drew a bonus pass tag. NR could have drawn up to 8 tags in the random pass but resident demand was high or NR were just unlucky and only 5 were drawn.
I estimate your odds for unit 6a at around 5-7%, 11m early at 7-9%, and 11m late at 12-15%.
Just because it's called the random pass doesn't mean the points are out of the window. People with 3, 4, 5, 6 etc all have a better chance of drawing than you do, but you do have a chance.
