Option 1:

Excel Formula:

`=IF([incredibly long formula]=0,NA(),[incredibly long formula])`

Option 2:

Keep the formula as-is and then create a second column Column2 with the formula:

Excel Formula:

`=IF([@[Column1]]=0,NA(),[@[Column1]])`

I assume Option 1 is the worse of the two since it necessitates calculating the incredibly long formula twice for values that are not equal to zero. However, Option 2 has the disadvantage of increasing the size and complexity of the table. What is the correct approach?
