Nostrodomus Predictions - Is There a Way Forward?

Last episode, we noted some of his predictive work he did for the queen of france. In 15 55 Catherine had invited him to the court to provide horoscopes of her children. He stayed a few weeks fulfilled his obligations and predicted that the queen would see all her sons acceed to the throne. When investigating psychic phenomena, the real question isn't about individual hits or misses. It's what pattern emerges over time? Is there any way of making this kind of assessment of nostrodomis?
