I disagree that it is exceptional- Martin Armstrong has so many ways of being right that it becomes useless. I call it the Gann fallacy:
https://images.exchangerates.org.uk/uploads/012319gas.png So many ways to be right isn't a good thing. He also hyped some date last year and then when nothing happened, he talked about some insignificant corruption that happened in Malaysia, which has never been a big player on the world stage.
I didn't say MA is exceptional, I only said it would be exceptional if you had reliable timing for events/moves (either up or down).......we are not in disagreement at all. Yes I have seen him countless times come in after the fact and stating all sorts of reasons why he was still correct. His ECM and arrays stand alone so if they work then it should produce an event on that date, if not then obviously it doesn't work.
