Nice as an inventory with plenty of "how about that" effects, but quite mechanical (is a period of one month hyperinflation worth mentioning? It depends on the months before and after) and without an attempt to analyse, let alone draw conclusions. The definition of hyperinflation looks random to me, as I suspect that the cut-off value of 50%/month was based on the number of toes the authors have on each foot, rather than anything scientific.
