Conclusion
Weights of 1.3, 1.6, and 2.0 all showed no difference from weight 1.0. Weight syntax has no effect on breast size increases.
No weight syntax effect was confirmed on this model. Unlike stacking (layering multiple adjectives like massive tits, enormous boobs), changing the weight of a single token was not effective.

What Was Tested
Whether the Stable Diffusion-style weight syntax (huge breasts:1.3), (huge breasts:1.6), (huge breasts:2.0) increases breast size. As a comparison, (massive breasts:1.6) was also tested.
For the huge breasts (weight 1.0 equivalent) result, see the summary article.
Experiment conditions and base prompt: see the summary article.
Results
(huge breasts:1.3)
![]() | ![]() | ![]() |
Comparable to huge breasts at weight 1.0. No size increase from the 1.3 weight was observed.
(huge breasts:1.6)
![]() | ![]() | ![]() |
Even bumping to 1.6, results are comparable to weight 1.0.
(huge breasts:2.0)
![]() | ![]() | ![]() |
Even at the extreme weight of 2.0, no change.
(massive breasts:1.6)
![]() | ![]() | ![]() |
Same result for massive breasts — no size increase from weight syntax.
