So good to go back to some of the original articles from Coach.

Allow a negative outcome to be the outcome.  Not every study has to prove the original idea (or worst plan B, C or D).  
The idea of registering what you are looking for before to do the study is also potentially an avenue.  

Not to sound nit-picky, but I'm pretty sure "PT" is a protected term in most US jurisdictions for "physical therapy" and in the article it seems to be referring to "personal training."

It would be great for CrossFit to take on the overspecialization of athletes in high schools that result in injuries, and how a year round GPP based strength and conditioning program (specifically CrossFit) can help correct that.  Also, to take on obesity and inactivity in the k-12 environment.
