Hi all,

does anyone have recent examples of spreadsheet functions truly misbehaving with real-life realistic data?

I am not talking about for example the cases of standard deviations or variances that went funky when the application was fed extreme data ranges, or similar waterboarding of software, which was debated 10 years ago and which led regulators to conclude they were the only ones who could be trusted to make proper use of such pernicious creations.

Realistic.
Data.
Only.
Please.

I will leave it to the reader to quantitatively define what "realistic" and "recent" actually mean and I reserve the right to challenge the definitions, obviously

Of course I ask because I never thought spreadsheets were or are as bad as their reputation. The users, on the other hand, are every bit as bad as their reputation. This certainly includes myself. Most likely I am the worst. But that will be the topic of another thread
