March of progress
Without mentioning any confidential details, one of the programs we use here at work has gone cheerfully insane. The numbers it gives us are neither the helpful ones we want but know it can't quite provide, nor the less-helpful ones it's supposed to, but a brand new set of numbers midway (but not halfway!) between the two, selected seemingly at random. I just spent half an hour with a notepad now covered in numbers and a calculator just making sure everything still adds up.
