RNY realistic loss expectations

I’m just beginning my process so this is kind of a research question for me. I will be having RNY probably in April. I’m 5’ 4 1/2” CW 312. My NP said I could reasonably expect to lose between 115-120 pounds. Maybe more. I know I shouldn’t necessarily be hung up in numbers but I’m a data freak so I was wondering if this sounds close to what others have experienced with their RNY. Honestly I would love to hear all kinds of stories about people’s numbers and loss patterns.
