You can tell Dr Kim to limit the increase. He can shorten the vocal folds by only 30% or by up to 50% - However, their analysis of the voice is more comprehensive than what one can do at home with praat , I think, so it can be that something else will come out. Dr Kim definitely does not want anyone to leave there with a voice that is too high. He sent back some people who had already female range voices because it would have gotten them into the 260Hz+ range and he also takes into account your body size - a very big woman with a tiny high pitched voice is odd, so he is open to all kinds of concerns.
My feeling from the little experience I have now is that pitch increase is not as dramatic by "force", but it is easier to use higher pitches. I guess if I want, I can later on easily speak at 230 Hz, but probably I will rather use a 180 Hz range (started at 134 according to Dr Kim). But we'll see. A lot of the perception about pitch in the ear of the listener ist also timbre. If I talk at the same pitch (according to PRAAT) now compared to pre-op, it still sounds higher pitched becauser the low undertones are gone.
I think Dr Kim really is an artist, he will know what to do and answer all your questions and adress all your concerns. I have not yet met any doctor in my country who tool as much time to listen to me and my concerns and then actually adress all of them. I think you can trust him
