I will say, though, that I have been repeatedly surprised when creating large, complex models for others in Excel at how easy it is to have a bug in your "code" that isn't obvious. In this respect, it's a bit like JavaScript's philosophy of "don't crash or sound an alarm, just make your best guess and keep going." For simple things, this works fine, but for anything complex, I really prefer more "bondage and discipline" from the platform, so my potential errors are pointed out rather than forgiven.
>complex models for others in Excel
It's best not to do that except in cases of emergency, I think. If you are going to get complex, SQL may be a much better solution, or something else.
Why not short it to "7-2"? Or even just "5"?!
The whole thing smells like good old Microsoft bashing and/or poorly disguised advert for Google Sheets.
