Hello
I would say that I am a type 4 to 5 and a stage 3.

Hi John, this is a better representation of Tanner Stages of Breast Growth. 

The 5 stages of breast growth:

Stage One
Technically starts when the hypothalamus in the brain secretes gonadotropin-releasing hormone (GnRH), stimulating the pituitary gland (also in the brain) to secrete follicle-stimulating hormone (FSH) into the blood circulation. That stimulates the ovaries to produce estradiol. Visually, Stage One is defined as that which is happening from birth until some enlargement occurs in the nipples and areolas. The breast glandular tissue is referred to as a breast "bud" at this stage. All of the components of the breast are there, but they are quite small, as they have not yet developed. Development in the female will usually begin to occur at the onset of puberty. A male's breast will usually remain in this stage throughout his life. (Unless NBE or HRT is chosen)

Stage Two
Is when breast development occurs after the breast bud has begun to change and shows some enlargement. The nipples will increase in size, often causing some embarrassment due to their appearance under clothing. The areolae will begin developing to a larger size and may start to slightly darken in color. The nipples become very sensitive at this time, and may have more sensations. During stage two is when the first menstrual flow (menarche') usually occurs, about two years after breast development.

Stage Three
Specific breast features are somewhat arbitrary, and stage differentiation is subject to the professional that is making the judgment. Stage three is obviously between stages two and four, and general overall enlargement of the breasts, nipples and areola occurs. Professional experience is usually used to decide where stage three starts and finishes.

Stage Four
Often indicated by the formation of a secondary swelling just under the areolae. It is almost as if a second breast bud is developing on the front of the existing breast. This can be seen during the early teens, or as late as the early twenties.
 
Stage Five
Is when the breast is fully matured. Changes to the breast will continue to occur throughout the rest of a woman's life, but they will be caused by pregnancy, lactation, weight loss or gain, aging and disease.
