    Whether 91% accuracy is acceptable depends on how unacceptable the 9% inaccuracy is. If 91% of the information in your term paper is correct you’ll probably get a decent grade, but if you only kill 91% of cancer cells the surviving 9% will grow a treatment-resistant tumor and you’ll probably die. This makes percentages essentially useless - more important is how badly wrong the worst wrong result is.
