Consider using the Tracking table. It allows you to enter actual start (Feb 1). Actual and remaining duration - which will calculate % complete.



If the remaining portion of the task will not be completed as scheduled (following on with Feb 2) then you need to split the task and reschedule the remaining duration to a more realistic time frame.

Another suggestion to avoid the split task - is to create the beginning part of the work as "preparation" and the remaining 20 days as another task.

For this excercise the works ahead doesn't really matter as that is simple enough. It is the past that I want to get recorded correctly.

Maybe some background info will help. Our company does roads and earthworks and we typically needs to remove an amount of material (basically dig a hole). The work carried out is measured as a volume and the resources utilized doesn't matter as no one is interested in anything except the volume. It is however important that we know when the quantities were dug out so we need the history to be shown accurately.

In the image below I've tried to show 17% of the work carried out over 4 days. Can MS project handle that?
