Alright fine, I can't prove my case. Guilty as charged. Regardless.. if all you have is "could be" and that's your argument for NBC to change, they've got a bridge in Brooklyn they'd like to see you. If you want irrefutable proof that the NBC way is the most profitable there is, you're right, you're not going to get that. Even still, the evidence and the reasoning that says it does work far out-weighs whatever argument you seem to have that they're better off doing it another way (again, other than Twitter). If the burden of proof is on me and you think anyone at NBC can or should buy into "could be" because you say they should with barely a shred of reasoning why it actually could be, then which of the 2 of us is the one hiding behind an Internet forum screen name.
