Unfortunately, this reminds me of things that track economic cycles and try to claim there is something meaningful to typical historical lengths of time between economic booms and busts. They often focus on the detail of "x years" without successfully tying it to something meaningful and then come up with mathematical models based on that and then you see books or articles predicting the next recession because "we are due/ it's that time" and those are somewhat often wrong. It is somewhat unusual for me to see meaningful analysis of underlying causes of such things. I'm mostly not a big believer in "well, x amount of time passed" as an explanation for much of anything. (Like with anything, there are exceptions.) I also dislike the use of your in the title, which contradicts the statement in the article that these are averages and your experience may be different.
