Project summary actual duration or % complete lower than those of the sub tasks
I have been tracking this schedule for a while. Just noticed that the % complete or the actual duration of the Project summary task is lower than those of the sub tasks. Why is this weird behavior ? ...

Nothing weird happening like John-project said but if you are still not satisfied with his answer, can you please paste a screenshot that also shows Actual Duration, Duration, Start, Finish & Task Calendar.

I have attached the required screenshot.
Let's say that we have a project of one month duration (31 days).
Now we are at day 15, the project should show the actual duration as 15.
The other activities can show duration 15 or less, as they all are within this project. But it cannot be more than 15. Am I right?

I think you are interpreting the Actual Duration field as literally meaning a time span from the start to the current date but that is NOT what that field means. I suggest you hover your mouse over the Actual Duration field column heading. That will bring up a short description of how the field is determined. You can also hit the F1 key to bring up the help file for that field.

It seems you have different calendar for Project Summary to the Tasks & Sub-tasks calendar. Assign same calendar and see what happens.
Day 15 does not mean Actual Duration should be 15 days as one of the peeves with MS Project is that it allows tasks to be completed in the future. E.g. if a Task with 31 days is assigned 100% on day 15, MS Project will show actual duration of 31 days and actual finish date in future (day 31).
