At the ice rink in Molly's Game (2017), Molly fights with her psychiatrist father Larry after meeting him long time:
Father: It's funny how much faster you can go when you're not charging by the hour.
What does "go" refer to? I understand by saying "It's funny how much faster you can go when you're not charging by the hour," he is suggesting that therapy sessions can be more productive or efficient when they are not limited by the time constraints imposed by billing by the hour.
