Hello there, my team is around 11 people big, and we are facing some issues with the burn rate chart. During sprint planning, we create tasks and pick them from the backlog. After starting the sprint, we add many sub-tasks to complete the task or split the work between team members, hence falsing the result of the burn rate chart (often we end up having the same amount of task by the end of the sprint).
How can we improve this? Because often at planning time we don't know which sub-tasks we are going to add to a specific task and I think is very impractical to reach that point.
I was thinking if there's a way to ignore sub-tasks in the burndown chart, but I can't find it...
