Calculation
I'm trying to understand Excel's methods and rules for recalculation. My
workbook (very large about 9 MBytes) takes about 7 seconds to recalculate. If I change 1 cell which has 5 other cells which are dependencies Excel still takes 7 seconds. None of those other 5 cells have any other dependent cells. So what is taking 7 seconds? These 5 calculations are very simple and I would think that Excel smart recalculation would be able to do these 5 calculations in a flash. So clearly there is something else going on. Either smart recalculation isn't so smart or I don't understand the underlying recalculation method. Any help on this is appreciated. |
