π€ In Primavera P6, there's Physical % Complete and Duration % Complete.
What's the difference?
It depends on how the remaining duration is determined and how progress is measured.
It is the difference between manual and automatic.
Physical % Complete can provide more accurate forecasting. After entering an activity's percentage complete, you must manually define the remaining duration to estimate the forecast completion date.
Duration % Complete is often considered less ideal. After entering an activity's percentage complete, the remaining duration is automatically calculated. However, the At Complete duration will be calculated with decimal values, which could lead to forecasts which are incorrect or misleading.
