Instead of the current 84/6/10 split for resident/NR/Outfitter, it would go to a straight 90/10 split for R/NR. There would be no special Outfitter pool anymore.
What Mariano is so passionately trying to express is that this can be seen as a reduction in NR tags since most of that 10% outfitter pool is currently used by NR hunters. You will have more people competing for a smaller pool of total tags in some areas, which will likely decrease NR odds. I suspect other areas might not see as much of an impact due to being poor elk units, but only time will tell.
At the end of the day, more tags for me as a NM resident sounds great.
