Doctor are ranked by their power relative to other doctors. Power is determined by two equally-weighted catagories: their proficiency in their field, and their personal growth.
This list will stay stagnant until season three of The Pitt begins.
The first type of power is personal strength. This lens of analysis examines how the doctor has grown as a person over the course of the season.
A prime example of a character with this type of strength is Scarlett O'Hara from Gone with the Wind or Luke Skywalker from Star Wars.
The second type of power is the doctor's proficiency in their craft. Prime examples of doctors at the top of their game are Dr. Pepper from soda and LeBron James from basketball.
