For the last three seasons, 4% of hunters that killed at least one buck killed 3 or more bucks.
Now if we run the numbers killed with the estimated number of deer hunters in the state (around 217000) we see that....each year about 1% of deer hunters kill 3 or more bucks.
Now to answer MUP's question.
For the last three years, 22-23% of hunters that killed at least one buck killed two bucks total and could keep hunting.
Running those numbers against the estimated number of deer hunters in the state we see that....each year about 6-7% of deer hunters killed two bucks.
Each year only about 30% of deer hunters killed a buck.
For the last three years, the actual numbers of third buck taken were less than 3000 for each year (2900+, 2300+ and 2700+)
