Maybe you're right, but I'd challenge your middle paragraph.
When there are 10 students, they often have some common misundersetandings that can be addressed together e.g. they all want a review of Taylor's theorem needed to do electromagnetism, and they forgot it from high school. So I argue there is a lot of room for reusability of explanations.
