Those are all easy, and if you have a reasonably healthy panel and good office support and subspecialty access you may be able to churn out 40 a day. But if you have an older, sicker panel, or a panel with low health literacy, or are in a place where it may be difficult to refer certain issues, especially time consuming conditions like psych, then I think 40 patients is either going to be unsustainable or lead to you practicing very little actual medicine other than med refills and USPSTF screenings.
I'm probably biased on where I've trained though, all inner city areas with lots of poverty and therefore the patients in clinic tend to have multiple problems, most managed by us. I might have a different perspective if I had more experience with healthier populations.
