Yeah I figured you meant the linguistic rather than the mathematical sense of the !, but I chose to intentionally misinterpret that for comedic effect.

Would you mind explaining the excel joke? I’ve spent very little time using that program (I’ll leave it up to you to decide how fortunate I’ve been), so I don’t really get it

(un)expected factorial? 1,30767e12 wipes seems like a lot. I guess you never specified currency, but at an average cost of 3,0581e-11 per wipe, I’ll assume that that’s a pretty decent deal.
