Excellent research! Your research mirrors much of mine. But, I must say, you are much better demonstrating it pictorially than I. My natural way is to use words and pictures do the task much more effectively.
One thought. During a Kondratiev winter, there are great trading waves which occur. In many ways, it is a traders delight as big corrections (waves) occur both on the downside and the upside. For observation, review the Great Depression of 1929-1942.
As long as one has the temerity to " ride the waves" it is an unparalled opportunity to make money. The losers will be those who buy and hold thrughout the event. In the Great Depression, one who bought and held lost 90% of their 1929 starting value. A truly venturesome investor can also use inverse ETF's to play the "down waves".
