A good way to get a feel for the Stop/Start dynamic in Change Main Characters is to picture the Stop character as having a chip on his shoulder and the Start character as having a hole in his heart.

If the actions or decisions taken by a Change character are what make the problem worse, then he needs to Stop.

If the problem worsens because a Change character fails to take certain obvious actions or decisions, then he needs to Start.
