It seems to me that we need an explanation of how a content experiment works. So far, I don't think a course developer has a good sense of when to use one and how to do so, i.e. you put it into a unit at the point where you want conditional content. The experiment itself contains a section representing the content for each group of students. When a student views the course in LMS, they are shown only the content for the group that they have been assigned to. To the student, there is no indication that they are viewing an experiment, i.e. the display name isn't shown. It appears as if the content was defined directly within the unit itself. There are probably other aspects to this that need explaining before a course developer would be comfortable dropping this into their unit, but this would be a good start.
