You would be AMAZED what you can do with data. Though long, there is an excellent blog post
THE CONTROL GROUP IS OUT OF CONTROL. In it, the author describes a prestigious psychologist ,Daryl Bern, who tried his hand at "proving" parapsychology, and surprisingly, using the most rigorous methodology (Meta analysis of 90 randomised controlled trials) was able to demonstrate it existed. Bern's work is scrupulous.
The point is, he kept upping the scientific bar as more "proof" is demanded, and delivered everything that was asked of him. Personally I don't believe parapsychology exists, however, I cannot use a scientific data argument to refute his work.
I have no doubt whatsoever, the "science" behind Project Sunrise will assure the regulators to a highly rigorous scientific standard, that indeed the operation is safe, just as parapsychology has been "proven".
