This can be used when the CalculationMode is Manual. In Manual mode, when cells are dirtied, formulas referencing those cells will not be recalculated until Recalculate is called or RecalculateBeforeSave is True and the workbook is saved.
To force a recalculation of non-dirty formulas, use the Recalculate(Boolean) overload and specify True for the includeNonDirtyFormulas parameter.
