I understand the time line. Its just the German incident (imo) is the starting point for the entire economic period. You could actually argue that 1914 is the start, but I like to use the end of the war, because I think a lot of Germanys problems stemmed from the loser pays mentality after WWI, not to mention the crippling debt that Germany was already under to pay for the war. The stress just led to 0 confidence in Germany.
