First
@Wrestleknownothing great analysis! However, in my mind the issue is not settled. There are a number of assumptions you have to make in order to do this kind of analysis. Here these include things such as the lack of scoring is not based on the current wrestlers being better defensively than before, worse offensively than before, or much closer to being evenly matched so that counter takedowns are much more effective than before. If any of these assumptions (or others) are incorrect it could explain why the 3 pt takedown has not generated the results intended.
Next the 3 pt takedown was not the only rule change to be implemented. Things such as what is a takedown, interlocking fingers, and what appears to be a non-enforcement of stalling (among other changes) potentially had an affect as well. Potentially there was a change that is directly linked to the 3 pt takedown (in other words is a dependent not independent variable) which would further complicate the situation.
I think the assumptions are valid, but some of the rule changes have had a bigger impact than the 3 pt takedown. Overall I would say the conclusion is that given the other rule changes the 3 pt takedown has not been able to increase the scoring as intended... leaving open the possibility that if some of the rules are changed it might.
Once again thanks for doing this... no one else that I know of is making the factual analysis to help people understand what actually is happening
