Erik,
It is the same question.
I asked if anyone had evidence that this stuff helps players shoot lower scores. I meant, and think it was implied, Tour players but leave that aside for now.
You responded, to paraphrase, "yes, we have empirical evidence".
I replied to that asking for clarification that you have empirical evidence that these strategies reduce scores (again assuming the Tour player context was implied as that is where the conversation has d gone).
If you don't want to discussyour work, fine. Maybe it would have been best to just abstain from raising your hand.
I agree with MWP that it would be difficult to prove but not impossible to make a really educated guess. If a players overall skills (as measured by strokes gained statistics) haven't improved all that much but their overall results are better since adopting a strategic method you'd have a good case to make.
