O.K., thanks for the clarification. Now, here is my thought about Breast Memory.
Maybe it is, but I wonder if like most things... You initially break a barrier, or at least come close, it's easier to bounce back and finally over come the same barrier, or a bigger barrier.
It's like being an athlete. You start out slow, because you do not have the basics, or the wind to complete it... But the next day or week, you find that you shaved a minute off of your run, or maybe handle 10 more pounds... That's not memory, that is barrier busting.
