I am finding a major discrepancy between the opinion of how many points are left in a Milestone, between the library Milestone Burnup app and a custom list that shows the stories. I'm talking 55 points remaining, from the list, and 130 points remaining, from the app. We don't point defects and don't have stories with story parents, so I don't get how this could be happening.
Too bad the chart doesn't have drilldown, but in its absence I'd at least like to see the query in the source code.
