Dear Helmut!

❝ Where did you find that?

I have to apologize - it turned out that I reffered to the draft version . In two years the mistape was corrected (or someone improved its rounding skills :)

❝ I’m not willing to accept 111.11%. Heck, with an acceptable ∆ of 10% we get \(100(1-\Delta)^{-1}=111.1\dot{1}\) – nothing else! I will not forget my second-grade math only cause it’s claimed ex cathedra by the oracle. Had to swallow already rounding of the CI. Double rounding? Gimme a break!

Then why do we use 80,00? "Because in the former case the numbers look nicer and are easier to remember
Of course 111.00 is nonsense and should be forgotten.
