Btw, I had some private discussions about Armstrong recently. And the gist of it, is that I think perhaps Armstrong is applying the scientific method of building cause & effect hypothesis via his stochastic and pattern modeling of events in time, but it's disconcerning that he doesn't open source nor publish any of his work in sufficient technological detail such that real peer review could be done.
So it's possible Armstrong is a con artist, although his extensive knowledge of history and the full body of evidence, causes me to take him somewhat seriously. Yet I also remain skeptical.
He is applying his Pi model on the timing of whatever he follows. I don't exactly know how it works, but everything has patterns, and it's related to Pi.
Why would he open source his work for? That's his livelihood. He makes money with his work. You can access his data at a monthly cost, he provides that as a service. How is he a con artist, and con artist for what?
You can be skeptical, but when you state it's possible he is a con artist, give links to verify your claims.
