I want to indicate with a Jira report the distance between the date of completion of an issue and the estimated release date of the issue. It seems to me that each issue that is associated with a Sprint keeps this information that is shown in the bottom right corner of the issue summary page. This indicator that I want to create must count, month by month, the total of the issues that have belonged to a single sprint compared to those that have belonged to more than one sprint, considering that this second case is typical of issues that have not been completed in a single sprint so that they have gone, in a certain way, beyond the expected date of release estimated / decided.
