Considering that her entire outer shell is basically nanotech Demerzel can make those puppies as big or as small as she wants.
Yet she keeps them that big.
Every part of her design and maintenance is mathematically chosen by her, every move is precise - it's never shown what powers her but every motion she makes is made in such a way for maximum conservation of energy. She only every drops this methodology of motion in extreme circumstances (Day getting bombed on trantor in S2, re-starting Gaal's heart in the most recent episode).
Hell even when she was fucking brother Day in season 2 she still moved like a machine.
Anyway I think I've made enough of the premise now - Demerzel mathematically chose the size of those tatas to be perfect. The last survivor of the robot wars produced those to be the best booba for the human form.
I do however feel like we need more data from a human perspective. Demerzel needs to get topless more often, for science.
