The Plot Sequence report in Dramatica is most nobtable because the relationship between structural items appear to be inconsistent with the Dramatica structural model. As it says in the report itself:
"This report shows how dramatic tension makes itself manifest in a series of discrepancies between plot and theme, act by act.
Information about the relationship between plot and theme comes in two forms in Dramatica. When you begin creating your Storyform, you are presented with a "perfect world" view of your story in which plot is completely aligned with theme. There is no discrepancy between the two, and therefore no dramatic tension. This balanced view is most easily seen in the Theme Browser, available through a icon toolbar or Project menu.
Once you arrive at a Storyform, however, you have input information about how that "perfect world" is twisted and warped by problems and conflicting perspectives. As a result, plot no longer matches theme, and the two are often quite out of step with one another.
As your story unfolds, it is the discrepancy between plot and theme that clues the audience in on the nature of the problem at the heart of your story and tells them much about the ways in which such a screwed up situation might be resolved.
Use this report as a guideline to the kinds of thematic considerations which should be addressed in your plot, act by act for each of the four throughlines. By developing this series of plot/theme discrepancies, the progress of your story will reflect the dramatic tension of the effort to unwind all the tentacles of the central problem."
There's a simple answer for the difference between the static structural model and the plow of the plot sequence report, and a several more complex answers.
As you make choices to determine the storyform, the structure is twisted and turned like a Rubik's cube with rubber bands. The Plot Sequence Report gives a view of the twisted version of the structure as seen from the "inside" (subjective view), as opposed the normal way Dramatica presents it which is to twist the storyform to fit the structure. The storyforming choices determine how the thematic explorations are aligned.
