I wonder to which experiment in the Weimar Republic, Cathy Reisenwitz is referring to. The reasons for the high inflation until 1923 are very well understood.

And IIRC the German government knew that inflation would be caused by their policies, maybe they were surprised by the extent but certainly not by the inflation itself. Much more interesting was the sudden end of the hyper inflation through the introduction of the Rentenmark. Which wasn't an official currency.
