Very different countries.

The Netherlands for example got their last reset by completely losing the Dutch empire.

Also, some societies have flatter curves than others. That really maps 1:1 to your style and culture of living and where the priorities are.

If your priorities are to be the best as fast as possible (Germany) you will have less time between resets. If your priorities are "let's chill and wait until the coconut falls from the tree into my hand", your society might be able to have a far longer time between resets.

But in the end: It's an iterative process. Which means: There must be iterations.

This sounds about as scientific as phrenology.
