Currently I am back to my pre OP voice thanks to a stupid cold. Pretty much exactly 145 Hz in Praat , which was my old pre op relaxed trained voice, which is what I do now as well ("trained"=controlling resonance). This sucks, but it is clearly audible that I have a bad cold, so I think it will not change the "passing". If I had a cold like that pre OP, I would be at 90-100 Hz or something...
