The Subjective Story Concern describes the area of shared concern for the Main and Obstacle Characters. The Subjective Story Range and Counterpoint describe why they come to blows over it. The Main Character will believe the Subjective Story Range (or counterpoint) is the value standard that should be used when looking at the Subjective Story Concern. As a result, The Main Character will see the Concern in a particular light. In contrast, the Obstacle Character will believe the other Variation (Range or counterpoint) is the proper way to evaluate the Concern. Since this standard of measure results in different conclusions about the Concern, the Main and Obstacle Characters come into conflict. They use these two points as they argue over two issues: what should be done about the Concern, and which is the best way to look at it.
