We had an over-abundance of deer and plenty of good bucks long before MO instituted APR. This is the same game management system that brought deer heard back from almost nothing after the Depression.
The APR bill of goods was sold to MO hunters primarily on the premise that in years to come, we would have trophy bucks to compare with those in Kansas and Iowa.
In the end I think it comes down to whether you think more regulation is the answer to a contrived 'problem'- or that Joe Regular is an idiot because he shot a forkhorn that he actually has a tag for.
“Nine-tenths of tactics are certain, and taught in books: but the irrational tenth is like the kingfisher flashing across the pool, and that is the test of generals. It can only be ensured by instinct, sharpened by thought practicing the stroke so often that at the crisis it is as natural as a reflex.” ~ T. E. Lawrence
