How are looseness and capacity determined?

The first time I had vaginal with Utra (no condom) I ended up with 2 looseness and 64ish capacity. The next time I had her with the condom and my looseness went to 3 and capacity to 110. I'd guess that the condom balloon made them go up, but the bold you are now loose text happens right away after penetration (not after she fills the condom) and the scene says that her liquids get squeezed out of the condom with each thrust so I wouldn't think it should be enough to nearly double it since the no condom scene filled me enough to look pregnant.

Are the numbers arbitrary values that were set for each scene, or is there a formula based on size? Looseness seems like it could be directly proportional to the girth you take (so 3 = 2.5-3 inch girth). Capacity confuses me though. Is it length + cum amount with a hidden modifier?
