Chelsea Charms

[andrat2000]

Around bust was a bit over 66" , protrusion? was about 10.5 and circumference was 34".
Not major differences by any means, just goes to show that they fluctuate in size (and makes me speculate she has a "preferred" size range, probably due to practical reasons with clothing).

Based on these measurements, particularly the circumference one, I have calculated that Chelsea was approximately 10,500ccs, assuming you measured accurately. I used the formula for finding the volume of a sphere, and I do realize that Chelsea's breasts are not perfect spheres, but the formula should give you a very approximate size. At 34 inches, her breasts should be about 10.8 inches in diameter or, 27.5 cm in diameter.

You calculated it very good for a sphere, I'm at 10,800 cc for the 10.8 inches diameter. Since the diameter of circumference 10.8 inches and protrusion 10.5 inches is about the same, calculation with a sphere is quite reasonable. Maybe her base where her breast is attached to the upper body is a little bit bigger than the outer curves of a sphere you may add 1500 - 2000 ccm, which would bring her to ~12,500 - 13,000 cc's.
