If I place the 'Plans' viewlet on my dashboard and set the timeline to my project, I get a green and red progress bar showing progress in the current iteration.

If I hover my mouse over the green/red progress bar, figures are shown including 'Work Hours Done'. I would like to understand the exact calculation that is done to come up with that 'Work Hours Done' figure.

I assume it is as follows:

In an incomplete work item, scheduled for the iteration:
- Any time entered into the time spent field, up to the point where this time is equal or greater than the estimate. When time spent is greater than estimate, no extra time is added to the 'Work Hours Done' figure

In a complete work item, scheduled for the iteration:
- The hours entered in the estimate. i.e. if it was estimated to take 10 hours, but actually took 1 hour, 10 hours would be added to the work hours done figure

In a complete or incomplete work item that was not scheduled for the iteration but which a team member has worked on anyway and put time against (e.g. an unplanned, high priority defect)
- No hours added to the figure

Are these assumptions correct?

Also, is there a way of seeing the "green bar" and the "work hours done" figure for the entire project, rather than just the current iteration? I know they should be the same thing, but we have examples of team members working on work items outside the current iteration as they had been planned to be done later but it turned out they needed to be done earlier.

Many thanks in advance for any help.
