The number of years (929) it takes to “correct” the orbits of Jupiter and Saturn due to gravitational forces. That is, the orbit of Jupiter expands for 929 years, while the orbit of Saturn contracts. But then the trend reverses and Saturn starts to expand even as Jupiter’s orbit contracts.
For some phenomena in life, business, and the universe, it may take a long time for trends (both good and bad ones) to emerge and then reverse. It is best to keep in mind that some corrections of deeply entrenched trends might take years to reverse.
