    Yes they seem like reasonable metrics to me. But like you I don’t really know how to answer the question. But relative economic strength and influence are likely factors. So the post civil war gilded age would also been a likely point, which was the origin of my 150 yrs estimate. For 100 years, I figured post WWI was a pretty clear moment of relative strength.
