Advanced Formula Challenge #12: Results and Discussion 2

Last week I set readers the challenge which can be found here.

Such was the number and variety of responses to this challenge that presenting a detailed breakdown of one such solution – as has been the case for all of the first eleven in this series of challenges – would, I feel, be somewhat inappropriate.

For the majority of these challenges, it could be argued that there has been one solution which is indisputably “better” than the rest. Perhaps such an adjudication can also be made here, though to do so would certainly not be a straightforward exercise. What’s more, to pick just one of the many solutions would be to leave the rest – unfairly in my opinion – left on the sidelines.

As such, I would refer the readers to the many solutions in that post and to enjoy dissecting the varied and wonderful constructions therein. And to simply thank all those – Alex, aMareis, Maxim, John Jairo, sam, Jeff, Lori, Ron, Michael, Christian and XLarium – whose excellent contributions led to such a fruitful and inspiring discussion.

There’s evidently still much to be discovered in the world of worksheet formulas!

Another challenge to follow shortly. Watch this space!


  1. I’m in the process of writing up a brief breakdown for each of the major approaches, as I thought it would be a good supporting example for the book I’m writing to illustrate the old adage “There’s many ways to skin a cat”. (Furthermore, it underscores a key point I make in the book that participating in on-line challenges like this – or even just trying to understand the solutions – is a great way to learn new approaches, or see formulas/formula combinations in action that you otherwise would never likely try out. Basically, it’s free university.)

    I’ll post a link to a sample file here fairly soon that contains these write-ups, and will put them on the book blog in more detail too, once the book is launched. (Probably in a month or two).
