We create these reports by taking a snapshot of your projects. We store reporting trends for last week at the start of each week. This is how we get weekly progress reports. And this is the reason why we need Scheduled Tasks running!
This data – burndown, iteration, hours – is not updated during a week. So if you come back to these reports during a week, you will not see any updates. The only real time data is Most Active Tickets and Longest Open Tickets.
