I have a task that has two people working at 80% of their time on it. I have entered a task with work = 3 days. I expect the duration to be 3 / (2 x 0.8) = 1.88 days. But project insists that it is 3.05 days. I have this for a lot of other tasks in a project.
The task not effort driven and is in fixed units.
I really don't understand this. Can someone explain.
