Two approaches to remixing ...
I am not sure how useful is this distinction in practice with each adaptation exercise having its own properties. The point is to ensure consistency and continuity. The suggested subheadings (and any others?) under "Considerations" should cover most situations.
I agree that the previous headings should cover many situations. The purpose of the two approaches to remix was more from a project management standpoint and less about providing alternate outcomes. When I wrote that particular subsection I was envisioning a teacher combining 4-5 sources, acknowledging the need for consistency and asking "So how to I do all of that?" The material under that heading is the best generalized advice I could think of.
If you still feel its value is minimal, I will delete it.
