I understand what you are saying, however, the numbers you show don't really prove that the numbers increased due to making a high school division not just a 16U division. There is strong evidence that this is true but to really prove it and make it as resounding as you make it sound one would have to analyze the number of kids that were older than the 16U cut off. Then you would know for sure exactly how big of an impact that change had.
Now before you get riled up, I think the trend is correct.....by allowing older kids to wrestle, our numbers increased. But to be technically accurate on your percentage you need to do the analysis stated above.
Bottomline: I don't think it really matters. The number of kids participating increased and that is a good thing. Just leave it at that.
