Yup, I know that. I was not saying height alone will determine scale. I know the base adds height. And I know that scale involves the overall size. That's why I posted pics that has the apple as reference. SSC uses a sculpted apple in their pics ...so that stays the same. So you can use the apple in each pic to guesstimate the size of their torso, arms, legs, head to see if they could be the same scale or not. And that's assuming each female character I posted have similar height character-wise in their respective domain (in movies, comics, books, etc.).
In any case, I was just wondering out loud. No biggie if they are different scale. I'm not going to go search for Shaak Ti and Darth Talon. Well ...not yet, anyway. LOL
