The Sprint/Iteration Summary section is located at the top of the Detail Tracking page. It compares the rollup values in the current sprint with that of the last closed sprint. Here, you can interpret the progress bars to see exactly where you stand. Note that rollups of Detail Estimate, Done (the accumulated Effort) and remaining To Do at the backlog item or defect level and at the sprint level include any and all amounts entered for backlog items, defects, tasks, and tests.
