The Planned points and Accepted points shown here on the Milestone Chart have different values;
The Burndown Chart includes a total number of points for user stories and defects associated to them regardless of what milestone the defects are associated to.
The Planned points are the total number of points that are associated to the user stores and defects.
The Accepted points are based off the planned estimate count of all users stories and defects and are included when work items are in an accepted state.
The work items will not be included if they are in a state of defined. Only artifacts in a state of In-Progress or greater will be included in the count.
