Guys, stop making a big fuss out of everything.
Of course 1000cc extra on a 3000cc girl is a huge difference.
My response is to Andrat's post, where he would assume that the volume of beshine's implant shell and breast tissue would be around 1000cc. On HER this would be negligible.
Someone with 3000cc is 5x smaller, so relatively speaking, the implant shell and breast tissue would be 5x smaller too, so 200cc. And the difference between 3000cc and 3200cc is really small and negligible again. And yes, I know there are deminishing returns, but that's only on a small, negligible number.
It's basic math guys.
Such a test would at least give you a number, and you need to keep an 8% error margin in there. Which is normal and quantifyable. And yes, like oschkosch said it would not change the numbers much, it doesn't have to, except that it gives more credibility to those numbers.
