Ya you're friends are doing it wrong... All this will do is persuade the biologists to issue more tags for the unit, and increasing hunter competition...One thing I'll add to the discussion is that, even if survey responses were mandatory, it still doesn't mean they will be accurate. I know of people that always respond that they were unsuccessful regardless of whether they were out of fear that higher posted success rates would flood the area with more hunters and force them out of their spot. Perhaps those people are few and far between or perhaps they're not, I couldn't say. But regardless of the system that states implement, posted success rates aren't gospel as @idahohikker stated.
Unless you're talking about tags purchased for statewide use...
