You see in 1948 where it’s 4.5 and jumps to 9 a year later? That’s a 50% crash in a year

Next year it’s 15. In 1952 it’s already 28. In 1956 it’s 40, up from 28 a year earlier. Crashed again in 58, 62, 64, 72, 74, 75, 77, 78, 79, 81, 82, 84, 86, 88, 89, 90, 02, 03, 13, 15, 18, 19, 20, 22, 23

My previous 10 times comment was taking consecutive years as a single crash
