Over the Legal Limit?

Does anyone teach more than 150 kids per day or have more than five sections? I know James has eight Latin sections and Robert Harrell has 186 German students, but what about others? To me, 150 and five is just about as much as a teacher can handle, and yet I hear about teachers who are way over that safety limit. Are we to be punished for our successes in attracting students to our programs? Is this a trend to watch or an overreaction?
