Is this plus or five after a depression actually happens, after full recovery, after the beginning of the turn around, or some other mystical date?

Something happens once. Then again, 70 years later, it happens again - plus or minus five years. And that's it.

So after one repeat you claim a pattern - plus or minus five years?

According to that kind of pattern making, we should have had a World War in 1964 (plus or minus). Hey, 25 years after WWI we had WWII, so following your "pattern after it happens just once again" rule, we shoulda had WWIII around 1964.

I'd be more inclined to follow a pattern based on a 22 year solar flare cycle - at least that could affect whether and thus crops and everything else down the economic line.

Got any data to cross reference with Solar Flare activity?

How about El Nino instances?

I'm serious. That would be Very interesting...
