In Version report, the story points range shown on the graph always exceeds the story point that customer has committed in the stories.
- Commit certain number of story points in the stories, lets say 30 story points
- The graph shows the range of 0 - 35 story points
- Now commit more story points, lets say add 6 story points (becomes 36 story points)
- The graph will show the range of 0 - 40 story points
The graph will show the range of story points from 0 to the exact number of story points that user has commited (in this case 36), Thus, once user completes 36 story points, the percentage will show 100%
The graph increase the range of story points (becomes 40 story points). This way, the percentage of user's progress can never reach 100%, as it will always set a higher range of story points, more than what user has committed in the stories.
