Yeah in the CORE series it’s mostly about demonstrating and showing you concepts, not really about the optimal way of doing something, that workflow is usually on regular courses. That said, in Blender and in 3D, there are so many ways on reaching a goal, so many ways of going about something, that is not really an issue how you get there. You’ll see people doing something in one way and you’ll think, I would’ve done it this other way, and both will be valid.
