You're right here, but two a point. It's important that we establish differences in cultures, but a 4T is a 4T and the basic guideline remains.
I found the cycle to be true for Native Americans, who didn't even qualify for civilization status.

In this project, 1990 and I have covered hundreds of 4Ts, usually 2 per country. I don't know the exact amount at this point, but I believe there have been less than '5' 4Ts that did not have a "crisis war," whether it be an external war, civil war, or rebellion.
True enough, the exceptions have been in the form of an aborted crisis war, catastrophic loss in population, or a revolution (that could have been an aborted crisis war). 1990 can correct me on this, but I believe that this is it.
Point is, because these happen so rarely, we don't know enough about them. As I said before, in the case of EG, we don't have enough information, so I can't possibly make a decision on it.
