Project summary actual duration or % complete lower than those of the sub tasks

aneeshU1 You say it's weird. So what do you think the actual duration of the Project Summary task should be?

Keep in mind that summary lines are NOT tasks, despite with the literature may call them, t hey are simply a summary of data for performance tasks (subtasks that have resources assigned to do something). As such percent complete and actual duration for summary lines will be some form of weighted average for all the subtasks under them. The developers of Project chose the formula I showed as that weighted average.

Here's a simple example. Should the actual duration of the Project Summary task be longer than any of the summary tasks under it just because it's the Project Summary task? Answer, "no".

Hope I clarified it for you.
