The Pros and Cons of Megaformulas

If you followed the examples in this chapter, you probably realize that the main advantage of creating a megaformula is to eliminate intermediate formulas. Doing so can streamline your worksheet, reduce the size of your workbook files, and even result in faster recalculations.

The downside? Creating a megaformula does, of course, require some additional time and effort. And, as you've undoubtedly noticed, a megaformula is virtually impossible for anyone (even the author) to figure out. If you decide to use megaformulas, take extra care to ensure that the intermediate formulas are performing correctly before you start building a megaformula. Even better, keep a single copy of the intermediate formulas somewhere in case you discover an error or need to make a change.
