Approved for Lip Lift but how much should I have removed? (photos)

Hi, I was approved for the procedure and the consulting doctor (not my surgeon but I have seen his work) said the average amount for me is 3-5mm removal. Should I make sure not to get 3mm? I worry it won't be enough. 5mm seems very common and 4mm might be ok. I had a septo-rhinoplasty a five years ago and my lip did drop slightly. I had a little filler but not since June 2021. My Philtrum is 1.6mm. I have 3mm of tooth show of my front teeth. No downturn smile at rest.
