I am not sure if the math works out here. Unless they have also found a way to reinvest the output of this 40% extra productivity into more individual productivity which would be the real story.
I imagine this came from 1.4^10 = 28.9. This might make sense if they used the proceeds of the extra productivity to get more employees with equal productivity and so on..
