I'd say <5% go in the books. I don't persoanlly know a single person that enters deer.... and alot of big deer.True. ^^ I don't know enough to say what the number really is...but very few of the big boys I know of that have been taken over the last several years are registered anywhere. I would guess maybe only 10%-20% get officially recorded?? Whatever the real number is though...the "stats" are way low to what is actually happening in my experience.
I too think the "one buck rule" could really make a difference here in Iowa FWIW.
