If you select a different pre-defined view like “Sprints View”, you see your sprints and related issues including their story points on the Gantt-Chart: “target start” and “target end” have been configured as custom fields to contain the planned start and end dates. All of them have got a postfix ** to illustrate, that these contents are their content represents suggested calculations, automatically created based on story points multiplied by the sprint's hoursPerStoryPoints. If you have configured any hourly value/story point for this project within the project administration → Gantt-Chart → time equivalent, then that value will be used. Otherwise, hoursPerStoryPoints will be calculated as sum of story points of all issues of that sprint relating to the same assignee divided by the number of working days of the sprint to get an average.
