I've worked for a capitation mill before. They expect you to see 16-20 pts per day. You do everything, including hygiene. The norm is for you to see 3-4 new pts per hour, while you are doing one major production, which could be crown preps or Endo. It is expected that you can do a molar Endo, build up, and crown prep of the same tooth in 2 hrs, while seeing all the new pts during that 2 hrs.
The reason why your friend is seeing 5 pts per day doing minimal work is b/c the office doesn't have enough pts yet. Once it picks up, then the 16-20 number will kick in. Each DMO plan would pay the office $1000-$1500 per month. There could be around 20 plans out there. Essentially the office could get $30,000 per month for staying open, but after the doctor and staff salaries, and other overhead expenses, there's not much left for profit. Therefore, the doctor needs to produce massively for the office to make $$$. I got burned out after 8 months and left.
