Thanks for catching that Stevenator, that should say 3 to 9 and 6 to 12. I believe I stated it won't give you a cup size. What it does do is give you breast growth results on exactly where the breast growth is coming from, meaning side and/or outward growth. In this respect we can address if we need more progesterone (for side branching) or estrogen for forward growth. For example, my left always trailed my right breast growth by at least an inch. So I focused in catching the left up to the right and for the first time my breasts are symmetrical.

R 32x25=800

I can't tell you how excited I was when I measured. I think it's safe to say these measurements are close to being cubic centimeters...known as " cc ".

The bottom line as to why the need to use this measuring tool is to track your breast growth.
