I agree. She does sound indisputably feminine, but it's pretty clear something isn't quite right.
Personally, after listening to results from several surgeons, I'm getting convinced that going for maximum pitch gain risks sacrificing a lot in terms of vocal quality or just sounding natural.
I don't think that should be necessary. The whole "170-240hz ideal range" idea is a crock of crap anyway. What you really want is a surgeon who will create just enough of a change that your overtone series is refined and your 'default voice' is no longer masculine. Listen to the 2nd example (the one on the right) on the Colombian surgeon's page - she sounds much, much better and more natural than the first one, even though she doesn't have even nearly as much pitch gain.
I thought about asking Dr. Haben to take me as high as he could go, but decided not to - one, because I might be volunteering myself as a science experiement; and two, because I trusted that he has enough experience to make me sound natural (as he prioritizes) and didn't want to risk any loss of vocal quality. My hunches turned out reasonable. I'm very happy with my voice now and even when talking around ~140hz I still sound perfectly female.
