NExS uses natural order recalculation, which is a method of ordering the computations such that each cell's value is computed only after the values for all cells on which it depends have been computed. Natural order recalculation guarantees that cells are always computed correctly, regardless of the order in which the cell formulas were entered. Iconified sheets are recalculated the same as visible sheets.
NExS supports several recalculation options:
All four options are set in the Recalc Options dialog box.
