Is there a standard report that shows sprint completion percentage over time? The Sprint Report does not have a comparative percentage (i.e. team commited to 10 items (or 85 points) and delivered 9 items (or 77 points), for example. This would be 90% completion based on items and 90.5% in points. Or, if this doesn't exist "out of the box," is there an easy, repeatable way to do this without manual or external tools, such as Excel?
