I think you are right on, but I need to check my research if this is exactly how they submitted it to the FDA. Nevertheless if APF530 is approved across the board, HUGE! If only 3/4 then I don't think we see nearly the pop as with 4/4.
The other thing to consider is that I believe that if they are approved for any combination that their Biochronomer technology is implicitly approved, but I am not sure of this. No time to research now - got a day job - but if anyone knows the answer, please reply. Details on Biochronomer below:
