Lets see...I initally was going to say 10% but that really isnt quite right...that is 10 out of every 100 bucks, which is really what I estimate to be about the proportion of 3.5+ year old bucks to total bucks in my area...in other words, that would be any 'mature' buck. So...I would say 'top' end bucks would be around 2%...or in other words, the top 20% of mature bucks.
